Description
After changing the Coordinate Transformation Matrix of an input device the cursor start to jump around if you touch the screen.
The feature seems to work for the most part but has this annoying behavior.
I located the file where the transformation coefficients are processed. Maybe the problem lies here: xorg-server-1.10.3/dix/getevents.c:1077-...
