I haven’t yet learned how to replicate the bug, it keeps happening at seemingly random intervals. Right now it happened after walking away from my pc for a while, and when I got back it happened.
I find my taskbar (Set to be on the bottom) at the top, when I open the edit tool it says that it’s still at the bottom. The add widget button just doesn’t do anything. The notifications are at the middle of the screen (however they are set to be bottom right).
This all started happening after I updated to plasma6. I searched online and found that typing killall plasmashell && kstart5 plasmashell into alt+space fixes it for a while. But it’s not a permanent fix.
Also pre-update I didn’t had any problem with my screen going blank while watching Youtube, but now my screen goes to sleep when I watch fullscreen Youtube.
I’m sorry that I got no more information, if I should supply some logs or screenshots, please tell me and I will.
If your screen is turning black when you go full screen, try turning Adaptive Sync to Never. This has solved the problem for me.
System Settings -> Display & Monitor -> Adaptive Sync
I can’t seem to find that setting.
Check under Display Configuration, its at the top of the list where Gamma is in your screenshot. I’m also using Wayland, so maybe its not available for X11?
Edit: The archwiki might be more helpful, it shows how to access the settings depending on your set up https://wiki.archlinux.org/title/Variable_refresh_rate
