Bug ID: 515657
Summary: Kwin leaks memory when loading audio files in Audacity
Classification: Plasma
Product: kwin
Version First 6.5.5
Reported In:
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: performance
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
SUMMARY
Each time I open an audio file in Audacity, the memory usage of Kwin increases
and is never freed even if I close Audacity. I also observe hitches when I
change the accent color or the theme. Freeze duration is proportional to amount
of leaked memory.
I already opened an issue to the Klassy theme project thinking that the issue
was coming from there. (https://github.com/paulmcauley/klassy/issues/260). But
the memory leak also happens with the Breeze theme and Klassy removed from the
system and is way worse with the Plastik windows decorations.
I also opened this bug previously
(https://bugs.kde.org/show_bug.cgi?id=514810).
STEPS TO REPRODUCE
1. Open a file explorer in a directory with audio files
2. Open Audacity
3. Drag the audio file from the file explorer to Audacity and undo with Ctrl+Z
4. Repeat the step 3 multiple times, and see memory usage of kwin.
OBSERVED RESULT
Memory usage of kwin increases
EXPECTED RESULT
Memory usage of kwin doesn't increase
