Bug ID: 504801
Summary: Poor performance and lag interacting with panels in
X11.
Classification: Plasma
Product: plasmashell
Version First 6.3.5
Reported In:
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Panel
Assignee: plasma-b...@kde.org
Reporter: kde.entail...@passmail.net
CC: niccolo.venera...@gmail.com
Target Milestone: 1.0
SUMMARY
Sluggish and Poor performance and lag interacting with panels in X11. Does not
occur on Wayland. I have only tested this on Arch Linux. Mainly occurs when
opening programs from the taskbar but also can be seen when opening the
applications menu and in cursor loading animations.
STEPS TO REPRODUCE
1. Open up an X11 Plasma session.
2. Interact with the panel (mainly opening programs like system settings).
3. See the error.
OBSERVED RESULT
Jittery and laggy animations, delays in opening programs.
EXPECTED RESULT
The panel works smoothly.
SOFTWARE/OS VERSIONS
KDE Plasma Version: 6.3.5
KDE Frameworks Version: 6.14.0
Qt Version: 6.9.0
ADDITIONAL INFORMATION
On Wayland the desktop functions smoothly.
Setting the environment variable "QT_QUICK_BACKEND=software" works as a
band-aid solution to the problem, but does not fix it.
