1 out of 3 times when I lift my tablet pen out of range, it switches to one of the default presets, Basic_tip_default. It switches back when I approach the pen again but if I press the shortcut for "Previously selected preset" it will go back to Basic_tip_default, which is not what I expect.

I'm using a Wacom Bamboo Pen&Touch CTH460. I have checked with evemu-record, it does not look like the tablet is sending anything unusual those 1/3 times when I lift the pen and the preset changes.

Edit: Okay it's not happening anymore and I have no idea why. Cool, I guess.
