Bug 515657

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
