Description David 2022-05-13 09:46:21 UTC

SUMMARY
It's been a while since my latte dock started performing poorly, and even freezing when hovering during meeting calls or other GPU intensive tasks.

STEPS TO REPRODUCE
1. Start a meeting or some other kind of CPU/GPU intensive task
2. Insistently hover lattedock
3. 

OBSERVED RESULT
Latte is extremely sluggish and freezes the entire UI from time to time, which gets back to normal after a few seconds. The faster you move, the worse the lag.

EXPECTED RESULT
Latte should be fluid and in particular it should not freeze the entire DE.

SOFTWARE/OS VERSIONS
Operating System: Fedora Linux 35
KDE Plasma Version: 5.24.4
KDE Frameworks Version: 5.91.0
Qt Version: 5.15.2
Kernel Version: 5.16.5-200.fc35.x86_64 (64-bit)
Graphics Platform: X11
Processors: 8 × Intel® Core™ i7-8550U CPU @ 1.80GHz
Memory: 15.5 GiB of RAM
Graphics Processor: Mesa Intel® UHD Graphics 620

ADDITIONAL INFORMATION
I've noticed disabling tooltips on mouse hover completely solves the issue and restores lattedock fluidity. This is likely to be the culprit.

I dont know anything that Latte can do about it except to give you an option to disable them. I consider it upstream plasma libraries issue.

The app name tooltips. The ones you get when leaving the cursor onto an app icon ("tiny title tooltips on hovering").
