Bug ID: 431023
Summary: [patch] KWindowSystem does not respect the selected
X11 screen
Product: frameworks-kwindowsystem
Version: 5.77.0
Platform: Archlinux Packages
OS: Linux
Status: REPORTED

xcb: Work with the active screen as reported by QX11Info::appScreen().
SUMMARY
On a traditional X11 multi-head setup (e.g. two screens ":0.0" and ":0.1"
active), KWindowSystem ignores the screen it is run on and enumerates/manages
windows on screen #0.
The fix is pretty simple as it's just a matter of passing the correct screen
number to NETRootInfo::NETRootInfo().
STEPS TO REPRODUCE
1. export DISPLAY=:0.1
2. run https://github.com/jlindgren90/qmpanel
OBSERVED RESULT
qmpanel lists the windows on screen #0
EXPECTED RESULT
qmpanel should list the windows on screen #1
SOFTWARE/OS VERSIONS
