Title:
  Screen disappear and show chunks from memory

Status in xorg package in Ubuntu:
  Incomplete

Bug description:
  Don't know what's happening and what is responsible. I've installed
  Xubuntu 14.04 32bit. I'm working on 4 desktops (2 of them have
  Chromium with few Thunar and gedit and the other 2 have full screen
  emacs) and sometime when I do something in Chronium everything
  disappear and some part of the screen show current desktop and some
  show youtube video I was watching in the morning.

  I have ATI Radeon based laptop, default installation not properitary
  drivers (when I search for them I got message that it didn't found
  any).

  I read that my video card is supported by default drivers. lspci show:

  01:05.0 VGA compatible controller: Advanced Micro Devices, Inc.
  [AMD/ATI] RS880M [Mobility Radeon HD 4225/4250]

  For me it look like corrupted video memory that show different data
  (saved when I watch youtube). Maybe it's drivers fault. I'm able to
  fix the issue for a while when I click show desktop icon. Don't know
  what's triggering this, sometime it look like everything is working
  fine.

  Before 14.04 I had 13.04 64bit version and everything was working
  fine, didn't have enough space to upgrade. But back then I had ATI
  catalysis drivers.
