Samsung RF511 - background not refreshing in 12.04

[Magnes]

Adter update to 12.04 I have no wallpaper - instead everything that moves above the wallpaper leaves a trace on the background - it's not refreshing. I had the problem in 11.10 but there it was fixed by using ppa with newer intel drivers, I assumed it will be fixed in 12.04 but it looks it didn't and that ppa also no longer helps (it's the same on default intel drivers from 12.04 and on intel drivers from the ppa xorg-edgers).

Here is screenshot of the problem: http://wieza.iq.pl/media/screenshot.jpg - after last update though it got worse - Unity icons are gone and are black. Knowing Ubuntu it's a random problem and they will be back to normal after I reboot tomorrow probably though so it might not be the greatest problem.

I can't report it with apport because it crashes.

Technically not a driver bug - the issue is that having no background wallpaper, unity is not painting over the damage it creates as it moves the window around.
