DPI scaling is undeniably nice, unfortunately I never got far enough in my Wayland journey to see the benefits. Screen tearing is an interesting issue to parse, but it's also perfectly fixable in x11 if you force the compositor pipeline. Especially since my main monitor has G-Sync, I've not really noticed any tearing on Linux unless I use a desktop that explicitly lacks a compositor on an integrated GPU.

I really like what the Wayland people are trying to achieve, I just don't agree with their methodology, and their results have spoken for themselves.
