What you did

Compiled and tried to run atmospheric_fog demo. I have also tried breakout (also same problem) and combine-racers game (they compiled it and released as binary)

What went wrong

what were you expecting?

Graphical output

what actually happened?

It flashes the actual 3d output for a single frame then goes dead gray forever. Breakout does the same thing. Combine-racers doesn't seem to ever get all the way through init but doesn't crash either

I suspect it has to do with the nVidia drivers on linux. However, I have tried other 3D games on this machine (in F40 just like I'm using here) and they work fine. I have also played a number of games on Steam and they work fine too. It seems to be entirely a Bevy problem. Or, perhaps something upstream.

EDIT: I know someone will comment that I shouldn't test on the bleeding edge version and complain. Well, 0.14.2 also does the exact same thing.

Thanks for testing on both Bevy main and 0.14 :) Do the wgpu examples work for you?

collin80 commented 1 month ago

Yes. WGPU works fine. However, here is the odd thing, Bevy always tries to use the nVidia adapter in my laptop. This is the hybrid type where the laptop uses the built-in Intel but has a much more powerful nVidia as well. But, WGPU seems deadset on using the intel pathway only. I was unable to get the examples to use nVidia.

So, it seems the intel drivers work fine but Bevy insists on nVidia and WGPU examples insist on Intel.

I think I encountered the exact same issue but with the release version 0.14 from crates.io. Camera only seems to output static gray :/

Quick Edit: My AMD iGPU and Nvidia dGPU on my laptop both only output static gray. Soo x_x even worse
