--- Comment #61 from Walter Nicholls <wal...@nic.gen.nz> --- I haven't seen this problem reoccur for me in the last month. Maybe a software patch has changed behaviour: Kernel now 4.2.0-35-generic plasma-workspace at 4:5.4.2-0ubuntu1.1 nvidia-352 version 352.63-0ubuntu0.15.10.1 (I'm not sure which packages are actually relevant to this). Other family members with KDE computers haven't ever seen this, by the way, although my wife did have a problem which toggling Alt-Ctrl-F12 fixed for her. Something about the plasma bar getting corrupted? Could have been same issue. Fairly old Toshiba laptop with intel video. -- You are receiving this mail because: You are watching all bug changes.
