Bunch of bu... rather unsubstantial claims. Just installed fresh KDE 5 + Plasma , running Wayland session, with two displays having different DPIs (96 and 185), and Plasma menus on HiDPI display are blurry until I'm moving a mouse over them, then they magically are getting refreshed with proper resolution. Tell me about how Wayland is great and works out of the box, sure

Plasma 6 was released recently with man fixes and improvements for the Wayland session, which is now the default. So it may be worth to try it again.
