Funny thing - when Compiz settings in Unity are set like these of Classic-no-effects, the rate of bug occurrence decreases. Now brush freezes after 9-10 strokes.
Namely, I checked these ones in Utility section of Compiz (others should be unset): Bailer, Detection, Regex Matching, Session Management, Compiz Library Toolbox, Mouse position polling. ... in Windows Management section: Place Windows, Grid, Move Window, Resize Window. ... in General, OpenGL unchecked all flags and set Texture Filter to "Best". -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gimp in Ubuntu. https://bugs.launchpad.net/bugs/556670 Title: Can't click on UI elements in gimp (intermittent) To manage notifications about this bug go to: https://bugs.launchpad.net/inkscape/+bug/556670/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
