I don't think #Plasma6 is ready for prime time. When I open apps, the title bar goes above the screen space and I can't move or close the app or use the menus.
Oh boy! Please don't tell me it's not usable. There is no way around it when running Arch and it's derivatives. 😂
I don't know how long I can hold off on updating.
Under Arch it hasn't dropped to Stable yet, so unless you are running the testing branch, you won't have to worry. I think it took 5.27 two weeks or so to get to the stable branch after its "release," so you are probably looking at early to mid March. By then, we should also have Plasma 6.1 drop, ie, updates.
It is not making my day very good, that is for sure. Perhaps there is a way to run it under X11 still and that might help for me, I have an older machine.
