The pointer suddenly jumps approx. 20 pixels to the right and 10 pixels down, just to jump back immediately when moving the mouse VERY slowly, making it nearly impossible to hit any small icons. This happens every once in a while, it seems to be location related. I did an 'evtest' on the according event device, the mouse reports reasonably, only +1 and -1 diffs. Pointer acceleration is off. This didn't happen with earlier X versions, and it is NOT related to some (hardware related) jitter from the touchpad. xorg-x11-server-7.6_1.15.0-284.1.x86_64 xf86-input-evdev-2.8.2-35.2.x86_64 Any ideas where to start debugging that? Heard anything similar upstream? Does this sound familiar? I'll first try downgrading the evdev driver to the one from the distribution, but it's entirely possible the interface version changed so this won't be useful. Reproducible: Always Steps to Reproduce: 1. Move mouse around, slowly. 2. Wait until pointer starts jumping Actual Results: Pointer jumps back and forth. Expected Results: Pointer does not jump. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
