[Bug 1435641] Re: plasmashell 100% cpu on screen lock

[DimanNe]

I have recently encountered this problem again at my notebook.

System info:
plasmashell 5.5.5
OS: Kubuntu 16.04
Also, I have two (physical) monitors, and I noticed this problem began to arise after I detached/attached notebook from dock station or after hibernation

Backtraces, perf top:
I ran "top -H" and it said there are two threads on my system, which are eating CPU - plasmashell and Xorg, so here is "hottest" backtraces of these threads collected with
perf top -t 3136   -d 5 --call-graph dwarf (where 3136 is thread Id from top output)
Thread of plasmashell - http://pastebin.com/GPMkrWz8 (see text after RAW Paste Data)
Thread of Xorg - http://pastebin.com/ZH0x7F7i (see text after RAW Paste Data)
