  I think I have the same problem. After ALT+TAB it sometimes looks like the "shadows" created by ambient occlusion are rendered at the wrong spots and at the wrong sizes. Don't have a screenshot available since I disabled the option to solve the input lag. If it persists after build 256 I'll make a screenshot.

  I get this same bug to happen consistently by:
  
  Starting/Joining a game in D3D9 mode with Vsync disabled
  
  After you join a game enable vsync

  Which graphics card and drivers are you running, mate? I have this problem on AMD 5970x2/Catalyst 13.8 (BETA).

  Edit
  NVIDIA GeForce GTX 660. Just checked and updated drivers to 1.6.1
  
  Edit2: Updating drivers does not fix

  Can you guys confirm this is occurring on D3D9 Fullscreen mode exclusively?

  Hi IronHorse,
  
  I have an AMD Radeon HD7950 and have the same ambient occlusion corruption that is demonstrated in the screenshots of Dictator93. I also have shadow corruption which I posted in another thread (http://forums.unknownworlds.com/discussion/132405/strange-shadows-after-alt-tab).
  I have tested a few scenarios for both the ambient occulusion and shadow corruption.
  
  Scenarios resulting in corruption:
  1) Fullscreen, then ALT+TAB out and back in.
  2) Any window mode, then changing the mode to any other.
  
  Scenarios NOT resulting in corruption:
  3) Fullscreen Windowed, then ALT+TAB out and back in.
  4) Windowed, then ALT+TAB out and back in.
  
  I hope it helps tracing the problem.
