Description imax 2022-12-05 18:20:52 UTC 
- SUMMARY
When you run applications in a Wayland session as SuperUser, icons and elements are not scaled. E.g. Dolphin or YaST.
See attachments.
Global scale in my case: 200%

- STEPS TO REPRODUCE
open applications in SuperUser mode e.g. Dolphin or YaST

- OBSERVED RESULT
icons are too small

EXPECTED RESULT
icons properly scaled (in my case @200%)

Probably environment variables not propagating or something. That said, we don't support running apps as root/sudo. Apps that require it like YaST should be ported to use privilege escalation using KAuth or PolKit.

Does this work properly on X11, and it's only not working on Wayland?
Comment 6 imax 2022-12-06 01:46:00 UTC 
Wrong scaling is only on Wayland. But it's only the icons and elements. I think the fonts scale properly.
Comment 7 Nate Graham 2023-04-10 03:21:22 UTC 
Ultimately this is an issue in those apps, not a problem in the Plasma setup process. They need to be ported to polkit privilege escalation rather than running as root/sudo.
