Example code Nice red circle : a lot of errors in the console but game is running

[Retrodad0001]

THE CODE: (as in the example)

use comfy::*;

simple_game!("Nice red circle", update);

fn update(_c: &mut EngineContext) {
draw_circle(vec2(0.0, 0.0), 0.5, RED, 0);
}

the flood of errors:

I had this issue also in bevy and could only fix it by choosing the renderer manual . I saw the same errors popping up in the video from gamefromscratch about this engine ;) https://www.youtube.com/watch?v=1w9f2-pyHtc&t=7s

im not an expert, but this could be related to : wgpu bug: gfx-rs/wgpu#3959 that was created by someone of the bevy team

Possibly related gfx-rs/wgpu#4247, seems there's a bunch of strange issues around AMD/Vulkan/DX12/Windows/OBS.

Surprisingly forcing either DX12 or Vulkan backend fixes it in the case when I reproduced it with OBS, but using the default backend doesn't work, even if the default ends up being DX12 or Vulkan. Very strange. I'll keep this open so that we can track it and related issues, though it doesn't look like it's a bug in Comfy itself, but rather somewhere upstream.

One of the next steps here is just updating wgpu to latest version. It's likely not going to help, but just in case.
