Main branch panic & COPY_SRC error

[turboMaCk]

Running examples panic for me. I'm on Linux (NixOS) using amd-gpu (open source driver).

relevant parts:

There are 2 things I believe:

a) how is it possible that I see the error even when I run examples which do use the helper
b) the panic might be related to some issue of development version of bevy

upstream issue bevyengine/bevy#3288

[StarArawn]

Yeah the COPY_SRC isn't the issue here, although it doesn't help its being spammed to the console though..

[turboMaCk]

I was able to pin down the reason for panic - it's upstream issue in bevy specific to opensource amd-gpu drivers on linux.

I think that's all we can do here. I'm not sure if you want to do something about that error log as well but I think it would make sense to have separate issue for it anyway. For the panic we just need to wait for fix upstream. Current workaround is to switch to proprietary driver. A bit painful but it's the only option at the moment.
