I use arch BTW!

I read the whole thing, our system is fucked.

I’m using KDE and when I download a flatpak it automatically creates a .desktop file. I think gnome does this too if I’m not mistaken. I do have to restart or relogin for it to put the file there but that’s not that bad IMO.

I have had a problem where some apps will just open to then show up as black. I can’t seem to figure out why its not working. It is what it is.

Not sure if this will fix your problem but try Wayland and see if you have the issue. I don’t know why a lot of my problems with games were fixed and it might help you.

Librewolf is able to do that by turning sync on in the librewolf settings.
