> Linux isn't in position regarding display/UI. It doesn't handles HiDPI (e.g 4K) screen uniformly, leading to a lot of blurry apps depending on the display abstraction used (Wayland/X11) and compositor (GNOME, KDE, etc, all behave differently).
I have been using a 4K display for years on Linux without issues. The scaling issue with non-native apps is a problem that Windows also struggles with btw.
When I still used windows (until windows 10) I always had to download some DPI fixer program to fix blurriness in many native windows programs.
Text rendering × DPI seems to be one of those difficult problems.
Windows struggles even with native apps, as soon as you have monitors using different scaling settings.
I'm currently using a laptop (1920x1200, 125%) + external monitor (1920x1080, 100%) at work. The task manager has blurry text when putting in the external monitor. It is so bad.
