I had this problem after the November update. Running 9.10, i386, 32 bit, nvidia video card. It occurred because I run the monitor at less than full resolution. I did not have this issue originally on 9.10. The only workaround I found was to use the full resolution of my monitor, which I did not want to do. I removed gdm and loaded wdm, which allows me to change the screen resolution without a login loop.
