Panic on shutdown in X11: EGL_BAD_DISPLAY in eglDestroyContext

[rcorre]

Bevy version

dd15890

[Optional] Relevant system information

If you cannot get Bevy to build or run on your machine, please include:

cargo 1.75.0
Linux 6.7.3-arch1-2

If your bug is rendering-related, copy the adapter info that appears when you run Bevy.

2024-02-06T12:38:40.591703Z  INFO bevy_render::renderer: AdapterInfo { name: "NVIDIA GeForce RTX 3080", vendor: 4318, device: 8726, device_type: DiscreteGpu, driver: "NVIDIA", driver_info: "545.29.06", backend: Vulkan }

You should also consider testing the examples of our upstream dependencies to help isolate any setup-specific issue:

The following does not have the same issue:

cargo run --bin wgpu-examples boids

I also tried running this winit example with no issue.

What you did

cd bevy/examples
cargo run --example animated_fox --features x11

What went wrong

The example runs fine, but on closing the window I see:

2024-02-06T12:40:59.051614Z ERROR log: EGL 'eglDestroyContext' code 0x3008: EGL_BAD_DISPLAY error: In eglDestroyContext: Invalid EGLDisplay (0x59e18f2fc450)

Additional information

I'm using the dwm window manager, and closing the window using a keyboard shortcut.

[BD103]

From a brief Google search, it appears this is detected by eglGetError which describes EGL_BAD_DISPLAY as:

EGL_BAD_DISPLAY
An EGLDisplay argument does not name a valid EGL display connection.

I have no idea what that means and I couldn't find any more information online.

I am also experiencing this issue on Kubuntu 23.10.

This is caused by #11660.

[doonv]

May be related to gfx-rs/wgpu#2165.

Looks like #11737 fixed this issue! I can no longer reproduce the issue after this PR.

[rcorre]

Confirmed #11737 fixed it for me as well. Thanks for the quick fix!
