Bug ID: 406307
Summary: Desktop always unresponsive after dragging windows to
maximize them
Product: plasmashell
Version: 5.15.4
Platform: Ubuntu Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Desktop Containment
Assignee: se...@kde.org
Reporter: rubs...@gmail.com
CC: plasma-b...@kde.org
Target Milestone: 1.0
SUMMARY
I'm running KDE Neon User Edition.
After recent upgrade to Plasma 5.15.4 now every time I drag a window to the top
edge of the screen to maximize it, the desktop *always* becomes unresponsive
for exactly 13 seconds (I measured several times using my smartphone's clock).
After that, the window usually maximizes normally.
Now, for me, this bug persisted since I started using KDE Neon (which was
around Plasma 5.12.*, I believe), *HOWEVER* until the recent upgrade (to
5.15.4) it the bug was occurring just occasionally. It worked without freezes
most of the time, so I could live with that.
Now the bug always persists, which kind of make system unusable for me (I'm
looking into downgrade to 5.15.3 at least).
STEPS TO REPRODUCE
1. Attempt to maximize any window by dragging it to the top edge of the screen
(the option "Maximize windows by dragging them to the top edge of the screen"
should be enabled in System Settings > Desktop behavior > Screen Edges)
OBSERVED RESULT
Desktop always becomes unresponsive for 13 seconds, after which window is
maximized properly.
EXPECTED RESULT
Window maximized by dragging immediately.
SOFTWARE/OS VERSIONS
KDE Plasma Version: 5.15.4
KDE Frameworks Version: 5.56.0

ADDITIONAL INFORMATION
I have multi-monitor setup, but bug is reproducible even with one monitor
disabled.
Disabling Compositor has no effect.
