Bug ID: 407458
Summary: Window minimize animation misplaced with
PLASMA_USE_QT_SCALING=1
Product: plasmashell
Version: 5.15.5
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: d...@dosowisko.net
CC: plasma-b...@kde.org
Target Milestone: 1.0
SUMMARY
When using PLASMA_USE_QT_SCALING=1 on X11 (as it's the only way to get correct
paddings and UI sizing in Plasma under X11 on a hidpi screen) and minimizing
window with a KWin effect, Plasma reports unscaled iconGeometry (in logical
coordinates instead of real pixels that KWin expects, like 200x850 instead of
400x1700 on 2x screen), resulting in wrong animations.
STEPS TO REPRODUCE
1. Use Plasma on a hidpi screen with PLASMA_USE_QT_SCALING=1 enabled
2. Try to minimize a window by clicking on the taskbar icon (with some
minimization animation enabled in KWin)
OBSERVED RESULT
The window gets minimized to some place in the middle of the screen.
EXPECTED RESULT
The window gets minimized to the clicked taskbar icon.
