Before I consider submitting any kind of bug report or details, I wanted to see if anyone else was seeing this behavior:
With a custom resolution set in system options for a game, and the toggle for return to default resolution on game close enabled, the system is no longer set back to the default resolution.
This was working January-ish timeframe, wasn’t around February to test.
If I have a game that doesn’t run at native resolution (e.g. old game), it doesn’t switch back or doesn’t switch back correctly (my window manager doesn’t like it).
If it’s not one where I can force it not to mode switch and use any arbitrary resolution (with old Doom/Quake engine or Unreal OpenGL games you can) I would use a “fshack” wine runner.
