I’m running KDE Wayland session on a Surface Pro 6 and the UI is much too small.
I changed the UI scale in System Settings which works for all my apps except for the system text (panels, menus, Dolphin). The text in my system UI is super blurry.
I’ve done a bit of research and it looks like Wayland may not support fractional scaling properly, but I’m finding conflicting info on this.
At this time, is it possible to run a Wayland session in KDE with 150-200% UI scaling?
200% definitely works, it isn't fractional.
Make sure it isn't image scaling X11 apps. That can cause blurriness if something isn't running in native Wayland. There's a setting in the display config about legacy apps.
The only things that are blurry are icons and text in KDE panels. Does that mean that KDE panels are not compatible with Wayland?
No, my KDE panels work fine, so that's not the issue.
Tried restarting?
Haha so embarrassingly enough a full restart fixed it. I was restarting KDE by command line and logging out and in because it seemed sufficient but not in every case.
The old turn it off and on again.
Yeah, some things check DPI when they start and then won't respond to changes or receive new environment variables. A reboot makes sure everything is using the newest settings.
