Bug ID: 468770
Summary: Disabling and re-enabling unscaled display in
multi-scale display arrangement makes plasmashell
blurry on the scaled monitor and causes popups from a
panel on the scaled screen touching the unscaled
screen's edge to appear on the unscaled screen
Classification: Plasma
Product: plasmashell
Version: git-stable-Plasma/5.27
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Multi-screen support
Assignee: plasma-b...@kde.org
Reporter: n...@kde.org
CC: aleix...@kde.org, notm...@gmail.com
Target Milestone: 1.0
Created attachment 158276

Display arrangement
Plasma 5.27.5 (git stable branch) on top of Fedora KDE 37.
STEPS TO REPRODUCE
1. Be on Wayland
1. Start with the dual display setup pictured in the attachment. The right
screen is primary at 200% scale, and the left is secondary at 100% scale (i.e.
unscaled). My only panel is on the primary screen's left edge, essentially
right in the middle of the whole arrangement.
2. Disable the secondary/left screen in the KScreen KCM
3. Re-enable it
OBSERVED RESULT
All plasmashell UI elements on the primary/scaled screen have become blurry.
Also, when I click on the Kickoff button on the right screen's panel, the popup
opens on the left screen.
Restarting plasmashell fixes both issues.
EXPECTED RESULT
No visual change to plasmashell UI elements; kickoff opens on the screen that
its panel lives on.
