Status in libinput package in Ubuntu: Fix Committed Bug description: I found this bug while cleaning my touchpad. Pressing and moving it, it started to move cursor until it stopped moving for multitouch gestures. While pressing and moving my finger quickly, Xorg crashed and it showed some colored and short lines on the upper left part of the display. This, if done again, forces to crash.
