I bisected the issue to #84976:

Another detail is the editor don't crash if you create a Node2D or a Control node:

https://github.com/user-attachments/assets/74d2a91e-8b03-4541-9056-4627d24b0aa1

Investigating futher i found that if you do any action that create the editor_layout.cfg file (creating a node and saving the scene or creating a node and reloading current project from Project > Reload current project) makes the project don't crash anymore, but if i delete editor_layout.cfg again or create the node but don't do any of the two actions i said above and kill the editor, the crashes come back.

I'm tentatively putting this in the 4.3 milestone / blockers that we track as it's a regression from a 4.3 PR. But I don't consider it high priority at this stage so close to the release, as it's a crash in the Adreno GPU driver and thus probably a driver bug. Figuring out a workaround might take a while as it might be difficult to reproduce.

Still, CC @DarioSamo who wrote the ARG PR, and @Alex2782 @m4gr3d @clayjohn who are used to debugging Android driver bugs.

[DarioSamo]

We have a list of devices that were affected by a similar regression. Perhaps this device just needs to be added to the detection here.

I say try forcing this particular workaround to true and see if it fixes the issue for you first.

i have a PR for Adreno 5xx uniform crash https://github.com/godotengine/godot/pull/92611

    //TODO: check 'driverVersion'?
    // no crash on Fujitsu F-01L - Adreno (TM) 506, Vulkan 1.0.61, driverVersion = 54185879

            p_device_properties.deviceID <= 0x5999999;

---

It took at least 3 weeks to isolate this crash via Firebase Test Lab and print_line. I don't own Adreno 5xx yet to debug it properly via Android Studio.

[Alex2782]

@matheusmdx To me it looks like an emulator, or is it something like a 'RemoteViewer' ?

This is a remote view, scrcpy: https://github.com/Genymobile/scrcpy. I used that to make the testing more faster, but i also tested without using this to make sure that didn't had any interference in the tests.

I can help test any possible solution, just gimme the instrusctions/apk. I also can try get a better backtrace if exists any way to get a more complete one,

[akien-mga]

You can get a backtrace with debug symbols by passing debug_symbols=yes to SCons (or dev_build=yes, not sure if it expects dev stuff) and building the apk with ./gradlew generateDevTemplate in platform/android/java.

Btw @m4gr3d we really need to document this on https://docs.godotengine.org/en/latest/contributing/development/compiling/compiling_for_android.html I see the page was updated to instruct using the new generate_apk=yes SCons option, but I suppose this only handles the stripped case and not dev templates?

We should probably still document the various Gradle task for advanced users.

[DarioSamo]

I changed for a hardcoded true but the crash persists

Seems we're pretty much in the situation of having to debug and find yet another workaround for a particular Adreno device because the Render Graph changed the order of operations then. Unfortunately the regression will point you to that particular commit, but it's just a situation of being lucky enough to not run into the driver bug before and now we are.

You can try messing around with these two macros and see if you get any different results, as these will make the render graph basically regress into the behavior of the previous version: https://github.com/godotengine/godot/blob/e343dbbcc1030f04dc5833f1c19d267a17332ca9/servers/rendering/rendering_device.cpp#L104-L117

[Alex2782]

My PR probably doesn't cover all editor functions yet, but the crash looks identical.

my old debug branch

void RenderingDeviceGraph::_run_draw_list_command For me it was more helpful at that time to output everything via print_line in order to compare logs with other devices.

However, you could also set PRINT_RENDER_GRAPH to 1, in which case the function _print_render_commands is used.

#include "rendering_device_graph.h"

#define PRINT_RENDER_GRAPH 0
#define FORCE_FULL_ACCESS_BITS 0
#define PRINT_RESOURCE_TRACKER_TOTAL 0

DrawListInstruction::TYPE_BIND_UNIFORM_SET

Issue description from my PR

An issue occurs when the vkCmdDrawIndexed function is called multiple times between vkCmdBeginRenderPass and vkCmdEndRenderPass, using a shader that includes a uniform variable (#define MATERIAL_UNIFORMS_USED enabled). The crash is caused if the subsequent render operations (Nodes) within the same render pass do not use material shaders with a uniform variable.

In other words, if a shader with uniform variables is used within a render pass, all following render operations up to the end of the render pass must also use shaders with uniform variables. Otherwise, this can lead to a crash. This workaround ensures that this does not happen by making sure that shaders with uniform variables are consistently used between vkCmdBeginRenderPass and vkCmdEndRenderPass.

---

Maybe we can add a better global solution in there somewhere. You could perhaps try to always execute vkCmdEndRenderPass after vkCmdDrawIndexed. And if the list has not been completely processed then run vkCmdBeginRenderPass again to check if there are still crashes. I may have time at the weekend to check the effects on my devices and see if the uniform crash can be fixed.

You can get a backtrace with debug symbols by passing debug_symbols=yes to SCons (or dev_build=yes, not sure if it expects dev stuff) and building the apk with ./gradlew generateDevTemplate in platform/android/java.

I tried this but ./gradlew generateDevTemplate just skip all the tasks and don't generate anything. The backtrace i put in this issue was generated using a apk builded with dev_build=yes and ./gradlew generateGodotEditor, i also tried using debug_symbols=yes instead but doesn't changed the backtrace.

You can try messing around with these two macros and see if you get any different results, as these will make the render graph basically regress into the behavior of the previous version:

https://github.com/godotengine/godot/blob/e343dbbcc1030f04dc5833f1c19d267a17332ca9/servers/rendering/rendering_device.cpp#L104-L117

Changing RENDER_GRAPH_REORDER to 0 stops the crash, changing RENDER_GRAPH_FULL_BARRIERS to 1 doesn't changed anything.

However, you could also set PRINT_RENDER_GRAPH to 1, in which case the function _print_render_commands is used.

Here what was printed, i just opened the editor and when editor loaded i triggered the crash: print render graph.txt

[Alex2782]

Thanks for testing!

Changing RENDER_GRAPH_REORDER to 0 stops the crash

I will revise PR #92611. Firebase Test Lab has up to 7 Adreno 5xx devices, on one device I could not reproduce the uniform crash.

    //TODO: check 'driverVersion'?
    // no crash on Fujitsu F-01L - Adreno (TM) 506, Vulkan 1.0.61, driverVersion = 54185879
    r_device.workarounds.force_material_uniform_set =
            r_device.vendor == VENDOR_QUALCOMM &&
            p_device_properties.deviceID >= 0x5000000 && // Adreno 5xx
            p_device_properties.deviceID <= 0x5999999;

I'm not sure exactly which driver versions they are.

            p_device_properties.deviceID >= 0x6000000 && // Adreno 6xx
            p_device_properties.driverVersion < VK_MAKE_VERSION(512, 503, 0) 

[DarioSamo]

Changing RENDER_GRAPH_REORDER to 0 stops the crash, changing RENDER_GRAPH_FULL_BARRIERS to 1 doesn't changed anything.

Pretty much fits the exact same situation of the other Adreno crash that the workaround was introduced for, where basically Godot was lucky enough to not crash on this particular hardware, but reordering the operations triggers the error in the driver.

The problem is not reordering the graph in this particular hardware would just be hiding the issue, because as soon as the renderer changes its behavior, it could reintroduce the error again. We're much better off investigating what exact sequence of events makes the driver crash here so the render graph can insert workarounds as needed, which would guarantee the renderer never breaks on this hardware in the future.

Without this particular hardware however, we're left pretty much guessing at this point. I'm afraid you'll have to dig deeper into it, probably by simplifying the project as much as possible and looking at the output of the render graph, and potentially modifying what looks like could be the problem. When dealing with a driver bug, we don't really have much left to review on our side as it's basically dealing with a black box where some behavior that is known to be correct just doesn't work.

One possible hint I'll give is that the previous crash was related to the relation between compute and drawing, and the old version was guaranteed to dispatch compute first before doing any drawing on the frame. Reordering can cause drawing to happen before compute, and that's what triggered the crash. You said you verified the workaround didn't fix it for you, but so far it's sounding like the exact same issue. I think it's probably worth double checking.

4.x Release Blockers and Status: Bad My suggestion would be to simply apply it to all Adreno 5xx, slightly (?) worse performance is still better than crashes.

Some stats / PlayStore Device Catalog

----------------------------------- `PlayStore Device Catalog` contains 1150 `Adreno 5xx` devices out of a total of 17339 (this is a share of approx. 6.63%) | Android API | Count | | ------------- | ------------- | | Level 33 (2y old, Android 13) | 2 | | Level 32 (2y old, Android 12L) | 1 | | Level 31 (3y old, Android 12) | 7 | | Level 30 (4y old, Android 11) | 75 | | Level 29 (5y old, Android 10) | 288 | | Level 28 (6y old, Android 9) | 275 | | Level 27 + 26 (7y old, Android 8)| 427 | | Level 25 + 24 (8y old, Android 7)| 191 | The older the Android devices are the more unusable they become, older Android versions also have older drivers and Vulkan API (1.0.x on Android 8 and 7). I think only from Android 9 devices Vulkan API 1.1.x is it worthwhile to invest more effort to fix exotic bugs. Up to 650 devices with Adreno 5xx GPU (approx. 3.75%). In Playstore, the installation figures would still have to be taken into account. For example, over 70% of our PlayStore customers already use Android 13+ devices, which is a "normal" app for ordering a cab. **Android 9 is even at only 2%!** 275 / 17339 * 100 = 1.59% * 2% * 100 = 0.0318% (?) of our customers could still have an Adreno 5xx with Android 9. 😃

We have driver (vulkan.msm8953.so) crashes on old Adreno 5xx devices:

According to your logs, it looks like a normal Godot issue libgodot_android.so. -> .NET / C# ? If no one has reported it yet, it would probably be more helpful to create a 'New issue'

@Alex2782 I searched issues, I dont think anyone else has reported it. I opened a new issue.

[matheusmdx]

@DarioSamo @Alex2782 I'll test the other mrp's and try find something. What i should look in the print render graph results? Like what result should be normal and what is a bug.

RENDER_GRAPH_REORDER = 0 -> no crash?

Yep, that stops the crash

[matheusmdx]

Also @akien-mga any idea why the debug symbols doesn't work? Get a full backtrace would help a lot.

[Alex2782]

What i should look in the print render graph results?

My recommendation is to render fewer frames:

func _ready():
    Engine.max_fps = 5
    print("======== READY ========")

https://github.com/Alex2782/godot/blob/debug_vulkan_shader/servers/rendering/rendering_device_graph.cpp#L642

Analyze what happens before the crash, but also what happens between several TYPE_DRAW_INDEXED and _run_draw_list_command executions. The Uniform (MaterialShader) crash can already be reproduced with 2 CanvasNodes:, I think it was like this:

• Crash: Node1 with UniformShader, Node2 without
• OK: Node1 without, Node2 with UniformShader
• OK: Node1 with UniformShader, Node2 with UniformShader

https://github.com/godotengine/godot/issues/82602

[akien-mga]

Also @akien-mga any idea why the debug symbols doesn't work? Get a full backtrace would help a lot.

Since you're building the editor, I think there's no pre-defined task for not-stripping it.

You could add the doNotStrip line from generateDevTemplate to https://github.com/godotengine/godot/blob/607b230ffe120b2757c56bd3d52a7a0d4e502cfe/platform/android/java/build.gradle#L284 Or copy it and make a generateDevEditor task for that.

CC @m4gr3d

[m4gr3d]

@matheusmdx you can generate a dev build of the editor with no-stripping using the following command build:

./gradlew generateGodotEditor -PgenerateNativeLibs=true -PdoNotStrip=true

For reference:

• -PgenerateNativeLibs=true generates all the shared libraries needed for the build. It's the gradle equivalent of the generate_apk=yes scons parameter. Note that it'll generate the dev, debug and release shared libraries so the build may take some time. If the shared libraries are already generated, you may omit this parameter.
• -PdoNotStrip=true disables stripping

For debugging the Android editor, I'd recommend using Android Studio. There's support for setting breakpoints both in java and c++ allowing you to walk through the code line by line to identify the source of the crash.

[m4gr3d]

You can get a backtrace with debug symbols by passing debug_symbols=yes to SCons (or dev_build=yes, not sure if it expects dev stuff) and building the apk with ./gradlew generateDevTemplate in platform/android/java.

Btw @m4gr3d we really need to document this on https://docs.godotengine.org/en/latest/contributing/development/compiling/compiling_for_android.html I see the page was updated to instruct using the new generate_apk=yes SCons option, but I suppose this only handles the stripped case and not dev templates?

We should probably still document the various Gradle task for advanced users.

Good idea, I'll update the documentation with instructions for advanced users.

Note that we'll need to merge https://github.com/godotengine/godot/pull/92859 to address a regression with how stripping is set in the latest versions of gradle.

[matheusmdx]

@m4gr3d I was able to build the apk with your instructions, now i just need some help how i do to debug using android studio, i tried use "attach debbuger to android process" but that didn't worked.

I also had some crashes where the debugger did not work properly, no breakpoints were positioned. Android Studio / Editor - Dev Build consumes an incredible amount of memory. At least 16 GB necessary, better 32 GB.

Because the error occurs in the driver, debugging is less useful: /vendor/lib64/hw/vulkan.msm8953.so (qglinternal::vkCmdDrawIndexed
