Hello,
   openSUSE v12.3
   linux v3.7.10-1.1-desktop x86_64
   gnome 3.6.2

   Ever since gnome version 3.2 the mouse movement becomes more uneven as
the logon time increases. Initially the movement is smooth and even as
expected. As the session time increases to 2+ days the movement shows
regular pauses (every 1 - 2 seconds) for some fraction of a second, then
"catches up" to where it would have been had it not paused. As the
session time increases, so does the jerkiness, i.e., the pauses increase
in length.
   This is annoying.
   Especially since the problem has worsened with later versions; the 
jerkiness increases after only a couple of hours. It has gotten so bad 
that I have gone to KDE where there is no such issue.
   It is related somehow to the build up of CPU usage on an AMD athlon 
quad processor. Initially the idle time usage is about 4%. As time goes 
by the idle usage increases to about 15% where the mouse action is so 
uneven that it is no longer tolerable.
   It occurs for two different mice, a wired unit and a wireless one. I
am currently using a Logitech MX300 mouse. Dis-/re-connecting the mice 
made no difference.
   The only solution so far is to log out and in again, or more 
recently, use a different desktop.

   Has anyone else seen this odd behavior?
