How are you? I installed the kde plasma desktop environment on archlinux, and I've been using it for quite some time. I have version 5.25.3 right now. I use the wayland session to work, play games, etc. Basically, everything works very well. With past releases, working with wayland become much more convenient. There used to be a lot of bugs that were just impossible to work with normally, but now the wayland session is just as convenient to work with as the x11 session. Even in the wayland session, everything seems to be working faster than in the x11. So, in the wayland session, I have one minor problem. 
When I leave for a while, the desktop is blocked, and after a while of waiting , entering the password, I'm on the desktop. It's okay, but I've got two monitors instead of one, and for some reason after unlocking, all the icons along with the desktop background go to another monitor. At the same time, if you click on a desktop(window, buttons, etc.) on another monitor, they jump over to another monitor. And so on and so forth. At the same time, if you don't do anything, or work as usual, then after a while, everything comes back on its own. Oh, yeah, one more thing. 
When the computer is locked, the periodicity image is turned off on both monitors, and then appears.
At the same time, sometimes one of the monitors may turn off. I don't know, but it might have something to do with the problem.
