--- Comment #4 from Andy <cress...@nycap.rr.com> --- FYI Just bought a new Acer laptop. Installed Kubuntu 17.10. Within a few hours the problem ocured. The only things I'd added were Vivaldi browser and Gparted. I wonder if something is writing to a memory position controlling the compositing. I've collected some more pictures and have the Acer specs. I've been running Kubuntu 14, but I want to put something new on the Acer. Got to move on. If you run into this elsewhere I be happy to answer any questions, but I think I'll be switching to Ubuntu. Good Luck Andy -- You are receiving this mail because: You are watching all bug changes.
