Hi everyone! this is my first post here!
I'm using Wine through Proton (and derivatives) to run launchers to play games.
I have found that if you put the launcher in a different workspace from the currently used one it will go black or have black glitches, moving the mouse over it will usually fix it.
Right now I'm using Battle.net to play Overwatch but I have seen this happening also for Epic's launcher in the past (using Heroic nowadays).
If you keep the launcher in the currently used workspace it won't do that, or at least from my testing it seems the case.
I have tested this on i3wm (with and without a compositor) and also with Ubuntu 20.04.
I was wondering if this was already reported, if it was taken in consideration for a fix etc. You know "knowledge is power" and stuff like that.
Thank you for your time!
