i updated to 12.10 beta 1 when it was released (coming from 12.04 fresh install, i skipped the alpha releases of 12.10)

since then i've done all the usual updates but ive had an issue with my cursor jumping. it does not jump when typing, i've done a lot of searching and cant find an answer, it tends to happen most when i move the cursor the jump is maybe 15-20 pixels down and to the right

it seems like a display issue because if i hover over a link or the x to close a window the cursor will settle in it's down/right position, but the whatever im hovering over will still act as if that's where the mouse is, and clicking still works on the item. so the mouse is actually in its original location, but it's displaying offset and flickering back and forth from its down/right position and its correct position

this makes use very difficult because the mouse is never displayed where it actually is and i have to estimate my clicks

any ideas?
