I’m still using X11 in Plasma. I tend to set the scale of my screen at 125% to 150%. Scaling in wayland Plasma is still not usable. The screen would be blurred. I searched for a solution and it seems that
this problem wouldn’t be solved in a very short period of time.
On the other hand, wayland in GNOME looks fine and it performs even better than X11.
