Description of problem:

The cursor does not render on the left monitor. When moved to the right monitor, it reappears. Note that the cursor, despite being invisible, still functions -- I can click, drag, manipulate images in the gimp, etc. The cursor itself isn't visible.

Moving the cursor to the right monitor works fine -- it reappears.

Version-Release number of selected component (if applicable):
* Linux desktop.averageurl.com 2.6.31.12-174.2.3.fc12.x86_64 #1 SMP Mon Jan 18 19:52:07 UTC 2010 x86_64 x86_64 x86_64 GNU/Linux 
* xorg-x11-drv-nouveau: 19.20091105gite1c2efd.fc12 


How reproducible:
Rarely, with no real "trigger." I encountered this once when manipulating rdesktop windows, and once after unlocking my desktop.

Steps to Reproduce:
1. Move mouse to left monitor.
2.
3.
  
Actual results:
No mouse cursor visible.

Expected results:
Visible cursor.

Additional info:
Rebooting fixes this.
