m-marti, is your mouse for some reason enabled as an extended device? If yes, disable it. You wont lose anything as mouse does not provide any extra info for extended devices.
As far as I am aware from my testing with mmiicc, it only affects extended devices and a specific event deliver mechanism known as event history buffer that is provided by X. It's a known source of trouble. According to my tests with mmiicc 2.7 does not exhibit this problem because of this commit: http://git.gnome.org/browse/gimp/commit/?id=dbf844c012894166e312470f0d98560d5e426613 With this I disabled the history buffer use because there are plenty of cheap tablet drivers that get it permanently wrong and 2.7 has event fill that prevents even mice from drawing polygons when moved fast, so milking every single event out of the device is no longer essential. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gimp in Ubuntu. https://bugs.launchpad.net/bugs/863154 Title: Wacom Bamboo One tablet random coordinate malfunctions Status in “gimp” package in Ubuntu: Confirmed Bug description: The tablet in overall seems to work correctly, with all pressure- features working. But quite frequently, while drawing, GIMP seems to wrongly read the coordinates of the stylus (as zeros, or negative values?), resulting in frequent, random 'line-peaks' in the direction of the left and upper image edges. With this bug it is hard to even use the tablet, since these problems are very frequent (see the exemplary image attached). The tablet works with no problems in MyPaint. The bug is reproducible in both Unity-2d and Unity-3d. I also notice the CPU usage increasing dramatically during drawing with any brush. Steps to reproduce: 1. Connect the Wacom Bamboo One tablet 2. Open GIMP 3. Start drawing longer strokes with any brush Expected result: The brush stroke as intended by moving the stylus Actual result: The brush stroke as intended with frequent, random line-strokes towards image edges System: Ubuntu 11.10 oneiric (development branch) GIMP version: 2.6.11 (package version: 2.6.11-2ubuntu3) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gimp/+bug/863154/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
