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

Icons are consistent when composition is on/off

Comment 3 Marcelo Bossoni 2020-05-05 01:00:54 UTC 
Forgot to mention that all apps that are closed after composition is turned off are not removed from taskbar
Comment 4 Nate Graham 2020-07-12 03:46:47 UTC 
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!
