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.
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.
