Panics in submit when running under X11

[ConradIrwin]

After the zed launch, we're seeing a number of crashes in ::submit:

• Aquire image error ERROR_SURFACE_LOST_KHR
• GPU has crashed, and no debug information is available.

It seems like these are exclusive (or at least very much more common) on Zed's X11 implementation vs the Wayland one, so I wonder if we've messed something up on our side.

I haven't seen this locally, but it happens across a wide range of linux distributions in the wild.

Do you have an idea for what I should look for to try and debug this?

[ConradIrwin]

See for example https://github.com/zed-industries/zed/issues/14225.

I wonder if it's specific to the combination of KDE + X11. Will try that tomorrow

[kvark]

That linked Zed issue sounds a lot like the Intel + Nvidia systems issue we've been looking at for a while, e.g. #88 It's a platform issue, and we have a workaround that basically make us not use the Intel GPU in this case. Users can confirm if it's a platform issue by running vkcube --gpu_number X to force Intel and seeing it failing as well.

We need to figure out the scope of affected systems and extend the workaround. Right now it's based on PRIME config - https://github.com/kvark/blade/blob/9e47628b59a18d1ca085ea9555c2d592864de642/blade-graphics/src/vulkan/init.rs#L113-L116

I wrote a general fix for this in #144. It's unfortunately verbose, but it should be 100% correct unlike the current heuristics.

I'd really like a strong signal from people having Intel+Nvidia configuration before merging. This includes both those affected and not. Here is what we'd need:

1. check out Blade #144
2. run RUST_LOG=blade_graphics=info cargo run --example bunnymark and share the output
3. of course vulkaninfo output if they haven't provided it elsewhere

@lemtea8 would you be able to try this out? cc @flukejones for ideas

@kvark Sadly the pr is still not working for my machine. What I got from RUST_LOG=blade_graphics=info cargo run --example bunnymark:

Thank you for testing, @lemtea8 ! The call stack of this failure is purely inside winit and doesn't have any of the Vulkan code, so it's possible you are seeing something else here.

[lemtea8]

It's interesting that I can run the examples in winit with the same version (0.29.15), but somehow blade fails...

[kvark]

Bunnymark example is trying to init a transparent window, maybe that's the main difference. But it's irrelevant to the original issue at hand.
