screenshot_and_photo_of_application
SUMMARY
I use Citrix Workspace across multiple monitors. After the last update the
second monitor only shows a mirror of the first monitor, without the mouse. The
application itself still believes it's on both monitors, as I can drag windows
to the second monitor and a screenshot with Spectacle also shows the output on
both monitors (see attachment).
STEPS TO REPRODUCE
1. Open plasma wayland session
2. Open application in full screen accross multiple monitors
OBSERVED RESULT
Second monitor displays a mirrored output of the first monitor.
EXPECTED RESULT
The application shows different output on each monitor.
SOFTWARE/OS VERSIONS
Operating System: Arch Linux
KDE Plasma Version: 6.4.3
KDE Frameworks Version: 6.16.0
Qt Version: 6.9.1
Kernel Version: 6.15.7-arch1-1 (64-bit)
Graphics Platform: Wayland
Processors: 12 × Intel® Core™ i5-10600KF CPU @ 4.10GHz
Memory: 16 GiB of RAM (15.5 GiB usable)
Graphics Processor: NVIDIA GeForce RTX 3060 Ti
ADDITIONAL INFORMATION
The second monitor is also temporarily visible, if I minimize the application
or something happens in the background, which affects the display, like taking
a screenshot with Spectacle.
It's still possible to interact with the application on the second monitor, it
just doesnt get displayed.
I don't have another program, which is designed to display across multiple
monitors, so I could only test Citrix Workspace. I updated only plasma and
kwin, so the issue should not have been introduced by a Citrix Workspace
update.
This issue only exists on the Wayland plasma session.
