[Bug 863154] Re: Wacom Bamboo One tablet random coordinate malfunctions
I use ATI graphics card without proprietary driver and still have this issue, so I don't thing it's graphics driver related .
There's a bug reported upstream for this problem: https://bugzilla.gnome.org/show_bug.cgi?id=661872

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)
