Bug ID: 456027
Summary: (Wayland) Dragging Panels between monitors in a
multi-monitor environment causes a hang (?)
Product: plasmashell
Version: 5.24.5
Platform: Manjaro
OS: Linux
Status: REPORTED
Severity: major
Priority: NOR
Component: Panel
Assignee: plasma-b...@kde.org
Reporter: p...@niburu.org
CC: niccolo.venera...@gmail.com
Target Milestone: 1.0
SUMMARY
Have looked round for an issue on this, but couldn't find anything that looks
immediately like a duplicate, so filing.
Dragging (docked) application menu bars between monitors in a multi-monitor
environment seems to cause at least part of the plasma shell to hang.
This is a 100% repro for me. Given nothing actually seems to crash I don't have
much in the way of crash dumps to provide, however I am also not running a
debug system. Its quite annoying, because my Wayland experience is actually
really damn good apart from this (cudos to the devs).
STEPS TO REPRODUCE
In a multimonitor system under Wayland after sorting out some monitor issues
after first boot into Wayland, I ended up with application menu bars on the
wrong monitor (I have a seperate one for each monitor, auto-hidden at the
bottom of each monitor)
I right clicked 'enter edit mode' on the menu bar, and attempted to drag it
from one monitor to another. As you drag it it attempts to attach itself to any
screen edges you come close to. After about two of these events, the taskbar
will disappear. The edit mode menu at the top of the screen remains, but is
non-functional.
If you can at this point get out of edit mode (alt-tab) then you can return to
the desktop, but no panels will be rendered, and it would appear that parts of
the plasmashell are non-responsive. Usually after this SDDM will not shut down
properly and have to be killed on shutdown.
Rebooting normally restores all panels, however the one that was being dragged
can occasionally get destroyed completely and have to be re-made.
OBSERVED RESULT
All Panels no longer rendered.
EXPECTED RESULT
Able to drag task bars between monitors.
