Can you explain what "breaks" you are experiencing?

I'm running Fedora/KDE/Wayland on two machines here, and the only oddity I get regularly is on my system with one monitor in landscape and one in portrait. Sometimes half of the landscape screen seems to be funky until I turn the portrait monitor off and on again (almost like it is trying to put the two displays on one for some reason). Most everything else has been flawless.
