It's a not uncommon problem of plasmashell process getting stuck and
deadlocked (often due to some as-yet-unexplained interaction between libxcb
and video drivers).
the easiest workaround is to restart the plasmashell process:
ALT-F2(krunner): killall plasmashell
(wait a few moments)
ALT-F2(krunner): plasmashell
I just had this problem again and restarting plasmashell didn't help.
Neither did dropping to console and restarting sddm. I actually
rebooted, which is unthinkable.
I have to tell you, MATE is looking better and better to me.
