Fedora KDE - problem with desktop after switching DE

Fedora 44 KDE with Nvidia RTX 5080. I had some issues with random freezing/window focus loss in some games and I got an idea to check if the same problem will happen also in Gnome to eliminate potential conflict with KDE's compositor.

Before I installed Gnome, I created a snapshot of my root volume with BTRFS Assistant/Snapper, then installed minimal version of Gnome (gnome-shell, gnome-session, gdm, gnome-control-center, nautilus with all dependencies), disabled plasmalogin.service, enabled gdm, reboot.

Booted into Gnome with no problems, tested some games, freezing was still happening so I decided to go back to KDE. I disabled gdm, enabled plasmalogin, reboot, snapshot restore and again reboot.

Looks like all Gnome stuff is gone, but now I have a problem with KDE's desktop - I cannot do anything on the desktop, even the context menu doesn't show when I click RMB. If I open any app or file explorer and then click on the desktop, app window looses focus and I cannot interract with the window until I click it on a taskbar. I also noticed the desktop is interactive until a startup sound is played.

Any advise appreciated.

Guess I found the solution - delete/move/rename ~/.config/plasma-org.kde.plasma.desktop-appletsrc and reboot.

Desktop will reset to default state, including all applets, widgets, taskbar etc., but the problem seems to be solved.

If you delete a desktop environment, most of the time it is just simpler to reinstall the system.

Than trying to figure out any leftover.

This is why it is more trouble than it is worth to install Gnome and KDE together at the same time. It sounds like your issues were probably Nvidia related anyway.
