I'm using Icons-only Task Manager with Minimize Animation. I have 15" 4K display with scaling 2.0. When I minimize application, animation ends at the location as if I had scaling 1.0. Eg. when my task manager icon is at 2100x300, animation ends at 1050x150.

Interesting. Currently I can't reproduce. I have a 4k display and use 2x scaling as well, and it's fine. We both have a single-screen setup, too. Your debug output says this for your screen, though: > Scale: 1 How did you configure scaling?
@Eike That scale line is for wayland scaling in Kwin. On X it will be always 1
Thx. In that case, I currently don't have an idea.
I changed it in System Settings / Display and Monitor / Displays / Scale Display. I also have following exports set so that also GTK apps scale well: GDK_DPI_SCALE 0.5 GDK_SCALE 2 PLASMA_USE_QT_SCALING 1 QT_AUTO_SCREEN_SCALE_FACTOR 0 QT_SCREEN_SCALE_FACTORS 'eDP1=2;DP1=2;DP2=2;DP3=2;HDMI1=2;HDMI2=2;VIRTUAL1=2;'
PLASMA_USE_QT_SCALING 1 That's deliberately not set by us on X.
Perhaps we should keep this bug open to track fixing the issue so we can eventually use Qt scaling?
Removing PLASMA_USE_QT_SCALING 1 actually worked and animation was placed correctly. However System Tray icons were smaller than expected, so for now I'm keeping PLASMA_USE_QT_SCALING 1. Thanks anyway.
We have a path forward for this now.
