Meshes and gizmos are not rendered on Android when using Mobile renderer

[TacoGuyAT]

Tested versions

• Godot 4.0.alpha6, Godot v4.2.1.stable, Godot 4.3.dev2.mono

System information

Godot v4.2.1.stable - Android Custom ROM RROS-Q-8.7.3-20211222-m1872-Unofficial - Vulkan (Mobile) - integrated Adreno (TM) 616 - SD710 (8 Threads)

Issue description

Godot 4 Mobile renderer seems to not render 3D objects and gizmos for me. Debugger output gets flooded with:

E 0:00:03:0294   render_pipeline_create: vkCreateGraphicsPipelines failed with error 5.
  <C++ Error>    Condition "err" is true. Returning: PipelineID()

When comparing RenderDoc captures to PC (both using Mobile renderer), the first render pass is empty on Android, while the rest seems to be fine:

Could you post the full error output from running this on 4.2.1?

With these errors it's usually the first few errors that are the most helpful so it would be good to see which ones happen first.

Do you mean some specific log file? The only thing I see is these logs in the editor (on Android)/debugger (on PC) output, which is this single error repeating over and over. Here's start of the logs:

System log also shows this shader compilation error (which could be it, I guess?):

It repeats before each of vkCreateGraphicsPipelines error 5

Can you try changing the rendering/limits/cluster_builder/max_clustered_elements project setting to 32?

I think it might help

Android versions below 9.0 have pretty broken Vulkan support (regardless of GPU), so it's possible that not much can be done about this. It may be possible to have a workaround that works for 2D only (or 3D without working reflections), still.

Oh, it's running Android 10. I didn't noticed when copying, but ROM name from Godot's info doesn't contain Android version, huh. By the way, Q in RROS-Q stands for version 10, which are official Android codenames.

Nope, still the same

After some experiments I was able to kinda launch the engine. Some Vulkan apps worked fine for me, but I've found out that the reason why these worked for me is because they ship Freedreno driver directly inside an app: https://github.com/PojavLauncherTeam/PojavLauncher/blob/v3_openjdk/app_pojavlauncher/src/main/jniLibs/arm64-v8a/libvulkan_freedreno.so

So while original ROM & custom ROM drivers both seem to fail on this exact spot, Mesa/Turnip/Freedreno (v23.0.4) one shows this in the editor:

Standalone games work better, but still lots of problems, though that might also intersect with Freedreno issues too: (Mobile, white and green squares are on-screen controls) (PC, intended look)
