Found another one with the same problem: http://ubuntuforums.org/showthread.php?t=142832&highlight=gimp+lag
That description is probably better, too: "have my Wacom Graphire 4 tablet working on Linux (Ubuntu 6.04, kernel 2.6.15, built-in tablet drivers) and get bad pressure sensivity and line quality in The GIMP 2.2.10, but at least it's working. However, when using any of the paint/ink tools, although producing a decent stroke, it fails to keep up. The stroke does not lag as if on a slow system, but if I end a stroke and quicky make another stroke, the second stroke does not appear. I notice that the CPU goes up to 100% whenever I paint with the paint/ink tool, and there's a slight cursor-lag at the end of each stroke, which I guess is why the system is not catching the next one. I'm sure this is not due to GIMP's inefficiency, as it works fine on my friend's much slower computer." -- Gimp lags and misses some strokes especially when drawing fast https://launchpad.net/bugs/41798 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
