KDE Plasma got a once-a-year notification that asks for donations a few months ago, which shows up in December.

I have tried Bazzite before and understand its appeal. I am an ex-Arch user so I prefer the system to be as minimal as possible. Fedora fits my requirements just right and Bazzite does not seem to bring anything to the table that I miss from Fedora.

Fedora Kinoite. I like KDE, atomic distros and the fact that Fedora is the only (at least that I know of) distro that has proper SELinux implementation.

I also play games on this system, so having newer kernel and Mesa versions help.

I suspect you have installed either Lutris or Steam through flatpak.

Try installing both using the same method or install MangoHud both as a flatpak and a system package.

Also, I recommend enabling MangoHud with ‘MANGOHUD=1 %command%’ instead.
