Bug ID: 461427
Summary: Native Wayland apps appear blurry after switching off
and on a display with scaling enabled
Classification: Plasma
Product: kwin
Version: 5.26.2
Platform: Manjaro
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: wayland-generic
Assignee: kwin-bugs-n...@kde.org
Reporter: cont...@programmi.st
Target Milestone: ---
SUMMARY
After power-cycling my monitor, Wayland-native apps are blurry (rescaled from
100% up to 200% by simple stretch), and X11-compatible apps are reset to 100%
scaling.
STEPS TO REPRODUCE
1. Log in using Wayland session.
2. If not yet, enable display scaling in KDE Settings: 200% in my case (I have
a single 3840x2160 screen), then re-login.
3. Open a few Wayland-native apps, e.g. Konsole, Doplhin, Settings etc.
4. Turn off your display. Then turn it back on.
OBSERVED RESULT
Native Wayland apps are be blurry, and XWayland-ed apps reset their scaling to
100% instead of 200%.
EXPECTED RESULT
Nothing should change about the scaling.
