GL backend crashing #7320
Description
Bevy version
v0.9.1
[Optional] Relevant system information
Debian 11
AdapterInfo { name: "Mesa Intel(R) UHD Graphics 620 (WHL GT2)", vendor: 32902, device: 0, device_type: IntegratedGpu, driver: "", driver_info: "", backend: Gl }
rustc 1.65/1.67
What you did
WGPU_BACKEND=gl cargo run --example custom_skinned_mesh
I was trying to use the gl backend, as I'm encountering issue gfx-rs/naga#1908, with all examples in vulkan seemingly continuing to run in the background, after I close my x11 window with alt+f4.
What went wrong

The app crashes. I found this: gfx-rs/wgpu#4455, but it doesn't seem like there's really any action to be taken around it.
Based on people's comments it sounds like intel integrated graphics under x11 are problematic with both vulkan and gl.
