Ambient Occlusion rendering breaks after alt tab

Dictator93

As the title states, AO renders incorrectly (and strangely) sometimes after alt-tabbing.

I will post my testing results for reproducability later this afternoon after coming home from work.
thx

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.
