Bug#998216: plasma-workspace: xembedsniproxy, Xorg and kwin_x11 use 100% CPU when I run two electron apps

["Patrick J." <patj@posteo.de>]

OK, I found something that resolved the problem for me:

I looked through the Plasma settings and found out that "Start 
compositor on boot" was unchecked for my user in the display settings. 
Enabling it again and restarting the session resolved the problem 
completely.
Another weird thing was that the file ~/.xsession-errors has a size of 
about 2.5 GB full of the message "Container window visible, stack 
below". This is introduced in plasma-workspace 5.23 if I interpret this 
link right
https://codesearch.debian.net/search?q=Container+window+visible%2C+stack+below&literal=1

Again, thanks for helping me out here. I think the bug can be closed.

Best,
Patrick
