You may want to try explicitly disabling Composite in your xorg.conf.  I 
recently experienced what sounds like similar behavior and composite was 
related.  See [1].  Clearly, the bug report is specific to xfce, but I believe 
other apps were affected in my case as well.  For the record, I'm running an 
nVidia card with the non-binary driver.
