Hello !

Yes I could have my custom preference working using steam, but there are a bunch of annoying stuff still :

1) drop down menu from separate tab (like when exporting a model) appears offset (sometimes on my other monitor ...) and can't be clickable. I have the same behaviour with other software like FLStudio using steam. I'm pretty sure it's not related to the OS, but maybe wayland.

2) I can't find a way to list Linux drive location outside the environment set by wine/steam

But we are a little bit in the "deaf leading.the blind" situation as I don't have much experience either.

However I still confirm Pop Cosmic is not ready for daily drive, at least not for my workstation (dual monitor + Nvidia RTX + AMD Threadripper), they are still too many crash/freeze/UI glitches.
They are update every day or so, that probably fix a lots of issue while breaking other stuff ... I do love that desktop, so I will give it an other try in a few months. (once it's no more in beta state).
