wgpu: wgpu examples don't work under Wayland when using OpenGL backend

Description As title. They work under X11. This occurred both pre- and post- wgpu-hal.

Repro steps WGPU_BACKEND=gl cargo run --example cube

Observed behavior wgpu master, on Wayland:

For what it’s worth, neither OpenGL or Vulkan work for Nvidia on Wayland (with the latest drivers that have improved Wayland support), but I think that’s an issue on Nvidia’s side… See also the issue on glutin. I’m not sure if it’s worth opening an issue for that on wgpu as it likely can’t be fixed easily here. On the other hand, there are OpenGL applications using EGL that run fine on Wayland with Nvidia, so maybe it could be investigated after all. As for Vulkan, wgpu simply reports that the surface capabilities are empty.

Firefox runs completely fine on Wayland with Nvidia since 91 though, including Webrender and WebGL.

Edit: with nvidia package version 470.63.01-2, the wgpu Vulkan backend works on Wayland 🎊

@kvark Thanks! Since NVidia seems to be more friendly about Wayland, I will try reporting this and see if something good will happen…

I can confirm that for nouveau it’s fixed, there is something wrong with resize events but that’s probably unrelated I will check winit for that. The rendering itself runs really well

The wayland fix is included in wgpu-hal-0.11.3

Our presentation is different, but that could be a good starting point. As I’m setting up a new system, I may be able to investigate in the upcoming month. But if you can start looking into this yourself, it would be most welcome.
