Comment 21 for bug 786317

I think we may have the first real interesting development on this just now - http://ubuntuforums.org/showthread.php?t=1795819.

This person claims that just by changing the Toolbox window settings (from having always show on top) the problem is fixed! Perhaps the way in which focus and window stacking are handled with the updated Compiz effects, the signals that should be getting sent to the main gimp window are getting sent instead to the toolbar window. Does that seem like a reasonable explanation?

Another discovery that I've had. I installed Gnome Shell on Ubuntu 11.10 and found that the tablet was working beautifully! At least, until I ran my little wacomsettings script (which runs a bunch of xsetwacom commands). Then the pressure response seemed to change, and the strokes became more intermittent (though not quite as bad as they tended to be with Unity). After rebooting back into Gnome Shell, things are working beautifully again. I haven't yet either tried rerunning my wacomsettings script (don't mess with what works, right?) or booting into Unity again to play around with things there (I'm kind of having fun with all the flexibility of Gnome Shell).

If I do and find anything interesting, I'll definitely share. Meanwhile, it would be great to have some independent verification of this stuff.

Cheers
