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

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

Thanks for trying to reproduce the problem.

This is my output of "top":

all other processes are below 1% CPU.

What are the steps to debug? Should I try to downgrade/remove a certain 
package? I did not want to try arbitrary steps breaking my system in the 
end.

What further data/logs can I put here?

Best,
Patrick
