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!
