can't lock screen, sometimes

good day. my problem in follow: sometimes when i lock screen there is no screenlocker, only the same what was on screen before i pressed Win+L. and i can't do anything. just stucked picture.

if i will switch to other virtual terminal and switch back there appears message contains "to unlock screen cast 'loginctl unlock-sessions' spell".

this is works for me. but i don't want to do this constantly. how can i fix this issue?

stuff: updated Arch with 4.8.11-1 kernel, KDE Plasma 5.8.4, KDE FW 5.28.0, Qt 5.7.0.

this is log from journalctl with working screenlocker: http://pastebin.com/Xq7c2h2H

Re: can't lock screen, sometimes

Does something crash?

man coredumpctl

to see if you get a coredump. What's your graphics card and driver? Did you have a right click context menu or a tooltip open when you tried to lock the screen? Afaik there are some X11 limitations that will prevent a proper lock when a context menu is opened
