--- Comment #19 from Dmitry Kazakov <dimul...@gmail.com> --- Hi, Ralek! Thanks for your detailed reply! The videos give a very little, but still some clues :) I will think about that in the background, perhaps I'll get some ideas. The video shows that the problem is not in the swapper thread as I though, but with something in the GUI thread. Because the thing that gets delayed is the brush outline, not the actual stroke. If it was the swapper, then only the stroke would be delayed, not the outline. If you happen to have more videos, please attach them, they might show me lots of stuff :) -- You are receiving this mail because: You are watching all bug changes.
