SUMMARY

The reason I switched to KDE wayland, despite it's shortcomings, is because of the staggering amount of applications that have no support for a DPI other then 96, as well as X11's shortcomings with multi-monitor setups (I like being able to set my second monitor to it's proper resolution while retaining the DPI it should have)

On that note, I'm also quite annoyed with applications being blurry. Ideally, it's arguable whether smooth scaling even needs to be used because some of these applications would actually look better using nearest neighbor scaling, but I digress: I think that the newest feature that lets you let applications handle scaling themselves is a welcome addition. But as I said earlier, some applications do not do this correctly. So while I hate the default scaling, it's actually a necessity for many programs...and yet, not others.

Alls this to say, I think that the "let programs handle their own scaling" option should be offered on a per application basis.
