streaking on the desktop

Description of problem:
This may be related to bug 577142
Whenever I launch an xterm process I get a window in which the text is messed up.  Rows of text will not all be the same height, and as the color block cursor advances to the right it "drips" color such that the rightmost characters are illegible.  Control-clicking for a menu causes that menu to leave residual vertical and horizontal lines, and sometimes dragging the entire xterm window around leaves streaks on the desktop.

Changing the text font (VT Font in the control-right click menu) eliminates the problem from that xterm for the rest of the session (any size change, even if I change it back).  It only seems to affect xterm windows though I assume it is a bug in mesa, xorg dri drivers or compiz...

Version-Release number of selected component (if applicable):
xterm-261-2.fc13.x86_64
compiz-0.8.6-1.fc13.x86_64
mesa-libGL-7.8.1-8.fc13.x86_64
mesa-libGLU-7.8.1-8.fc13.x86_64
mesa-dri-drivers-7.8.1-8.fc13.x86_64
xorg-x11-drivers-7.3-14.fc13.x86_64

How reproducible:
always on my laptop, haven't tested other hardware.  I assume there's some dependency on the graphics chipset.

Steps to Reproduce:
1.  Set up Gnome with Compiz on hardware using Mobile GM965/GL960 Integrated Graphics Controller
2.   start an xterm
3.   type text inside of it and move the window around.
  
Actual results:
garbled/compressed text, residiaul lines, garbage on screen

Expected results:
clean text rendering and motion

Additional info:
lots of other things may be relevant but I just don't know.  I have the wobbly windows effect turned on in compiz, for one.  I'm including all of my .Xdefaults that relate to xterm just in case:
