I have this problem here as well on Ubuntu 12.04 and 12.10. It only appears when using Unity (Compiz). Unity 2D (metacity), XFCE (xfwm), Gnome (gnome-shell) do not trigger the bug.

I have created a simple test program (adapted from the one provided in bugreport 1018600).

Compile: gcc mousetest-extended.c `sdl-config --cflags --libs` -o mousetest
Run: ./mousetest
Instructions: Move the mouse cursor to bottom right corner. If you are not affected by this bug, the programm will close automatically. If you are affected, the program will not close itself and you need to click any mouse button to end it.

Possible results:
1) Last line is "SDL is DEFINITELY working: 799,599": Everything is fine. The program has closed itself automatically.
2) Last line is "Extended area: $X,$Y": The mouse area got updated only partially. You had do click to close the program. You are affected by this bug.
3) Last line is "Original area: $X,$Y": The mouse area did not get updated at all. You had do click to close the program. You are affected by this bug.
