--- Comment #7 from Nick <nick.craig....@gmail.com> --- (In reply to David Edmundson from comment #6) > do you have an nvidia card? Did you just play a fullscreen game/video / > toggle compositing? Yes, Nvidia GeForce GTX 570M running the Nvidia driver 384.111. No, I never play any games on this machine. I had 4 instances of Dolphin open, kdevelop, Filezilla, Gimp, kmail, maybe Discovery. I've since rebooted and switched the panel to always visible to see if I can get the problem back again. -- You are receiving this mail because: You are watching all bug changes.
