Bug ID: 479822
Summary: Stuck dragging non-existant window after workspace
move
Classification: Plasma
Product: kwin
Version: unspecified
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org

Target Milestone: ---
SUMMARY
***
Short version:
Moving a window with a keyboard shortcut to a different workspace while
simultaneously dragging that window using the mouse leads to very strange
behaviour which almost forces a reboot.
Long version:
I'm running kubuntu 22.04 and make heavy use of its feature to use multiple
workspaces. I've created a keyboard shortcut to switch between different
workspaces moving the active/focused window with me. Recently I tried dragging
a window and then accidentally used the shortcut at the same time. This did
indeed move the application to the other workspace, but afterwards strange
things happened. My cursor still showed the symbol used for dragging a window,
but I could not see any window I was dragging. Furthermore, even when clicking
on other windows, I could not get focus on those windows. Some general keyboard
shortcuts, such as alt+tab, switching workspaces or opening the start menu with
the meta key still worked, but I lost focus on all those applications
immediately and was unable to do anything in those windows. I was able to
switch to a different TTY-session and kill plasmashell there, but that didn't
solve the issue. The only thing I could find that worked was running `sudo
systemctl restart display-manager`, which I think restarts either kwin or the
eniter X server? Not sure.
***
STEPS TO REPRODUCE
1. Set up a keyboard shortcut for 'Window One Desktop Down' (or other
direction)
2. Start dragging a window
3. While dragging, use the keyboard shortcut
OBSERVED RESULT
You're stuck in a state where you cannot focus any window and are seemingly
dragging nothing
EXPECTED RESULT
Yes
