i installed a dual boot for mint a little bit bac and just recently wiped out my windows boot partition. could not be happier. nobody try to sell me on any other distros I'm still figuring out what a wayland is
I had some wonkiness on KDE 6 on Wayland a bit ago, but I think it's resolved now (I ended up disabling scaling at the time). Basically, my problem was that I had two monitors, and dragging an application from one monitor to the other resulted in really weird scaling, though launching it on that same monitor was totally fine (specific application was LibreOffice, but I'm sure there are others).
I think it's working better now, but it's certainly new-ish to Linux, so there could still be hiccups.
