Stereo rendering issue?
Does anyone have any idea why this is happening when using the stereoscopic view in UDK?

The top and bottom parts actually flicker between what is shown and black (tried to get a screen recording, but it didn't actually show the problem. It recorded the tops and bottoms as just black without the flickering).
This is the first time I've seen this problem. I checked other maps I've created as well and they render just fine.
EDIT: Just in case it matters (not sure if it does considering other maps work fine), computer specs:
- 2011 iMac running Windows 7 in Bootcamp
- Intel i7 2.8ghz
- 12GB RAM
- AMD Radeon HD 6770M 512MB
I also attempted removing all the models + skybox from the affected map with no change in behaviour.
