Just installed KDE Plasma on my Ubuntu system to replace GNOME and Wayland. Mainly to get rid of an issue where my games would lose mouse lock, but now I can have two different wallpapers on both monitors and have a clock on my second monitor which is AWESOME.
I WISH I INSTALLED IT SOONER, I LOVE IT.


Did gamescope not do the trick for you? Having used both Gnome and KDE on Wayland anytime I’ve encountered that issue the solution was simply to use gamescope.
I only tried to use gamescope as a launch option, but that made it so at least one of the games wouldn’t launch. I’ve not tried with others though or installing it through apt. So far switching to kde has done the trick, so not going to try fixing a problem that isn’t there anymore (so far).
