SUMMARY

If I disable composition, items shown on task manager are not accurate.

STEPS TO REPRODUCE
1. open some apps
2. Turn composition off using Alt + Shift + F12

OBSERVED RESULT
Icons are not the ones of opened apps

Icons are consistent when composition is on/off

Forgot to mention that all apps that are closed after composition is turned off are not removed from taskbar

How bizarre. Cannot reproduce with Plasma 5.20 (i.e. current state of git master) an Intel iGPU.
Comment 5 Marcelo Bossoni 2020-07-12 20:30:30 UTC
I think that is the same as https://bugs.kde.org/show_bug.cgi?id=353983.
Comment 6 Nate Graham 2020-07-13 21:32:20 UTC
That turned out to be a bug with the NVIDIA driver. Are you using an NVIDIA GPU?
Comment 7 Marcelo Bossoni 2020-07-13 21:42:47 UTC
Yes,
I can confirm bug was solved with latest driver update
Comment 8 Nate Graham 2020-07-13 21:48:59 UTC
Excellent!
