JournalCTL logs from KWIN
SUMMARY
ALT + TAB becomes slower over time, taking longer and longer to display the
next window when pressing the combination.
STEPS TO REPRODUCE
1. Use KDE Plasma as normal for a few hours, alt tab frequently, I used
Audacity, and I closed it quite a lot while transferring sound files one at a
time from my local storage to my media server using the split view.
OBSERVED RESULT
You'll see a delay of 1-2 seconds when switching tabs that won't go away no
matter how many windows or processes you close. Everything else should perform
as expected.
EXPECTED RESULT
Alt + Tab not slowing down at all after several hours.
