Another example also crashes. I suspect it's my computer's fault😂

Example works fine on my system. Got 1 error but program continued running.

Not particularly knowledgeable about this (someone who knows correct me), but from what i could gather this is reproducible by just forcing GL backend WGPU_BACKEND=opengl cargo run --features wayland --example compute_shader_game_of_life. Someone confirm this error is not Linux-only.

The issue seems to be that GLSL requires textures formats to specify writeonly or readonly unless they are r32* (unsure if said formats still allow both operations though) and the shader has to write and read.

I tried changing the example to r32* but sprite pipeline seems to expect rgba8 format(?).
I guess the alternatives are either use 2 textures to avoid the readwrite requirement or put a warning on the example that GL backend is not supported.

On an unrelated issue, running any example on X11 and GL seems to be broken with a different error (invalid surface validation). I will create an issue once i get a bit more info.

I believe this is related to #7320
