Bug ID: 446627
Summary: Pager does not show correct size when
PLASMA_USE_QT_SCALING=1 is set on X11
Product: plasmashell

X11 desktop at 100%, 200% and with variable set
SUMMARY
On X11 desktops, when the environment variable `PLASMA_USE_QT_SCALING=1` is
set, the Pager widget only shows the first quarter of the desktop (in the case
of 200% scaling).
When the variable is not present, the pager works correctly when Plasma's
global scale set to 100% and 200%.
Wayland is not affected and works as expected, even with the variable set.
Perhaps there needs to be a condition to divide the global scale (e.g. 200% =
2) when X11 is in use and the environment variable is present?
STEPS TO REPRODUCE
A HiDPI display is useful, but not required.
1. Set the global scale to 200%.
2. echo "PLASMA_USE_QT_SCALING=1" >> .bash_profile
3. Log out and back in
4. Observe the Pager widget on the panel and open some windows in the top-left
and bottom-right regions.
OBSERVED RESULT
On X11 desktops, the window outlines on the widget are not accurately shown
when PLASMA_USE_QT_SCALING is set.
EXPECTED RESULT
The pager shows the correct position/size of windows for a virtual desktop.
