--- Comment #9 from Tyson Tan <tyson...@mail.com> --- Dmitry: Ubuntu 16.04 -- which I was using when I reported the bug -- has Qt 5.5.1 though. I'm running on intuos4+Cintiq12HD+1normal display (dual screen). I don't recall seeing this when Cintiq12HD was unplugged. I don't recall seeing this when doing very low-res pixel art (smaller than 640x480). -- You are receiving this mail because: You are watching all bug changes.
