Comment 75 for bug 1021517

I'm on 12.04, fully up to date, and the issue still occurs, so where's the released fix?
Initially when I first ran into the issue I thought it was the Nvidia drivers so I've tried all four versions available through 'Additional drivers'

Gimp: 2.6.12-1ubuntu1.3
Xserver-xorg-video-nouveau-lts-quantal 1:1.0.2-0ubuntu3~precise2
nvidia-331-updates 331.20-0ubuntu0.0.1
kernel: 3.4.0-47-generic

As a workaround I can unplug my usb mouse, but doing image manipulation with the touchpad isn't my idea of fun
