It works fine in Wayland KDE for me but sometimes stuff font rendering is bad on one of the screens when you move a window across. No problem at all in Qt (KDE) apps which look perfect at all times, but some others including Firefox seem more sensitive.
By the way, Windows also hasn't completely solved this problem, even OneNote (part of Microsoft 365) has horrible font rendering when you move it from a 150% scaling screen to a 100% scaling screen.
Change to the KDE Plasma desktop and it takes like 2 clicks
