Intuos3: press-and-drag with pen warps to corner on release

[Dave Ahlswede]

I'm pretty sure this is a new regression to Oneiric, as i don't always use my tablet as a primary input anymore, but basically, i have the problem that doing the tablet equivalent of a click-and-drag, i.e. pressing the pen to the drawing surface, moving it a distance, and releasing, seems to warp the pointer briefly to the upper left or upper right corner of the screen before the 'button press' is released.

The most obvious symptom of this is that when i click the titlebar of a window to move it, the window always jumps to the corner of the screen, making it effectively impossible to do basic window management.

This appears to be confined to devices in absolute mode; The problem doesn't happen when using the Wacom mouse, or setting the pen to relative mode. It's also specific to linux--the tablet functions just fine in Windows.

I initially thought the bug might be related to https://bugs.launchpad.net/ubuntu/+source/xf86-input-wacom/+bug/560180 , but applying the fixes from that to the Oneiric driver didn't have any noticeable effect.

Additionally, this only seems to apply to purely pen-tip actions; if Button1 is mapped to the rocker buttons, even with TabletPCButton mode on, the bug doesn't happen.
