Bug ID: 508619
Summary: Brief screen freeze when doing Present Windows
Classification: Plasma
Product: plasmashell
Version First 6.4.3
Reported In:
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: generic-performance
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: 1.0
SUMMARY
I have a performance issue with Present Windows on Wayland. The screen briefly
freezes when doing Present Windows (for anywhere from no freeze to 3-4
seconds).
I don't know the underlying cause but it seems to happen when I run JetBrains
IntelliJ IDEA in its standard X11 mode. The hanging behavior seems to get worse
over time -- after a few hours of active system use, Plasma hangs on Present
Windows can exceed more than a second.
After Present Windows is executed, doing another Present Windows immediately is
fast. But after only a few minutes of normal system use, it has the same
hanging issue again.
When configuring IDEA to use its experimental native Wayland mode, the issue is
not reproducible. Therefore, the problem seems isolated to XWayland. The only
other XWayland applications I am currently running are xscreensaver and this
does not appear to cause any issues.
This is a recent problem. I've been using this combination of software for a
long time and have never had an issue until recently.
STEPS TO REPRODUCE
1. Run IntelliJ IDEA for several hours using its default X11 mode
2. Execute Present Windows
OBSERVED RESULT
A Plasma freeze that can last several seconds.
EXPECTED RESULT
No hang / freeze.
