Alt tabbing.

[greatelmo]

On desktop environments such as KDE and Gnome alt tabbing and returning to the window absolutely destroys the window.

Does there happen to be a way to not have this happen (other de's do not have this issue)

[NelloKudo]

Can you test https://github.com/whrvt/umubuilder/releases/tag/proton-osu-9-12 and see if it happens there as well? Just replace the proton-osu folder in ~/.local/share/osuconfig with the one in the package.

[greatelmo]

No luck.
(it's gnome if that might help)

[NelloKudo]

I use GNOME myself and I can't replicate that, probably an NVIDIA thing?
For now, try using borderless. I'll see if I can replicate it somehow.

[greatelmo]

Might be Nvidia (3050 6GB)

Borderless does not have this issue (TESTED)

EDIT: Spoke too soon.

[NelloKudo]

Then use borderless, there's no difference between that and fullscreen on Linux. I'll see whether we can fix it (or Proton 10 will) xd

[NelloKudo]

OH it's still there in borderless? Sheesh 💀

[greatelmo]

This time only when I press insert to minimize
So at least we fixed that part.

Does it happen with the environment variable WINE_DISABLE_FULLSCREEN_HACK=1 set?
