[Bug 863154] Re: Wacom Bamboo One tablet random coordinate malfunctions

 

Here I finally ended to remove all , even if updating Xorg edgers and
use last Nouveau driver solved my problems, the performance of painting
were horrible. Also very slow painting strokes in _all_ 2D programs....

I fallback to a Linux Mint 11 Katya main , based on Natty system with  a
downgraded compiz ( http://www.webupd8.org/2011/05/how-to-downgrade-to-
compiz-086-in.html ) and a downgraded Xorg ( sudo apt-get install
xserver-xorg-core=2:1.10.1-1ubuntu1 ) . So a version in between Maverick
and Natty , compatible with Natty Ppa :) Works perfectly and damn fast.
My laptop will be ready for the conferences I have to do next weeks.

I also get issue with lake of customization / functionality with new
Gnome 3 ( I liked the base GUI, and ergonomy , btw )  ; it makes me use
too much terminal / GSettings / Tweaks and various code to access to
basic customization where Gnome 2 series were fast and mostly GUI
tweaks. ( login screen/ place icons on the dockbar/ nautilus script /
startup script / etc.... )  So, I felt a real regression.  I don't blame
Gnome team, new product is young compare to old 9 years old one, and
there is very good job in the 3. I blame modern distribution who pack it
while it's not a ready solution... imo.

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)
