Bug ID: 491153
Summary: When using two monitors, maximized XWayland
applications do not reach the top of the screen for
clicking
Classification: Plasma
Product: kwin
Version: unspecified
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: minor
Priority: NOR
Component: xwayland
Assignee: kwin-bugs-n...@kde.org

Video of the issue
SUMMARY
Some applications cannot be clicked at the very top of the screen when
maximized and using two monitors.
STEPS TO REPRODUCE
1. Plug in a second monitor
2. Maximize an XWayland application on the primary monitor (in the video
example, I use PrusaSlicer)
3. Click on the very top of the screen
OBSERVED RESULT
Clicking on the very top of the maximized app will instead click on what is
behind it, like the desktop or another app. As well, the close, maximize, and
minimize buttons do not reach to the top pixel when they normally do.
EXPECTED RESULT
Maximized applications should reach the top edge of the screen (which they do
visually, just not for user interaction)
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Fedora 40
KDE Plasma Version: 6.1.3
KDE Frameworks Version: 6.4.0
Qt Version: 6.7.2
ADDITIONAL INFORMATION
Not sure if it happens on all resolutions. For me, my primary monitor (on which
the issue occurs) is 2560x1600 and the secondary monitor (on which the issue
does not occur) is 1920x1080. The issue also does not occur if the second
monitor is disconnected. See video for a demonstration of the issue.
This issue is weirdly specific so I imagine there may be some issue replicating
it - let me know if there's any more information I can provide to help. I have
done some experimentation and narrowed it down to only apps running through
XWayland that do this - all other apps I tested worked fine and I didn't find
any XWayland apps that did not have this issue.
