[Bug 806256] Re: xf86PostMotionEvent resets cursor to upper left

 

** Description changed:

- occurs when pressing buttons on a wacom tablet. I am told this only
- occurs on ubuntu so it is not a problem with the wacom package
+ When a wacom tablet is used in X, pressing a button on the tablet causes
+ the mouse cursor to be warped to the top left of the screen.
+ 
+ Regression potential: Moderate.  The patch is small (and by our resident
+ input hacker), but touches the a codepath that all Absolute pointer
+ events go through.  Regressions should be easy to spot, however.
+ 
+ Original report follows:
+ occurs when pressing buttons on a wacom tablet. I am told this only occurs on ubuntu so it is not a problem with the wacom package
