Description Michael Seifert 2012-12-30 13:28:17 UTC 
The user should not be able to set the threshold for the mouse pointer to 0 pixels. Doing so results in pointer jumps as described in bug #219867 (see also comment 11 by me).

Reproducible: Always

Steps to Reproduce:
1. Set the pointer threshold to 0 pixels
2. Mouse the mouse pointer somewhere on the screen
3. Stop the movement for a moment
4. Continue the mouse movement
Actual Results:  
Mouse pointer will jump to the upper screen edge, left screen edge or upper left corner.

Expected Results:  
Mouse should move normally as expected.

Tested with xorg-server 1.12.4.

https://wiki.archlinux.org/index.php/Mouse_acceleration states that "xset m" does support 0 threshold value. If this does not work, it is a bug in the X server.
