Flickering Shadows

Hopefully the link works

Recently, today, I started getting some flickering of the shadows on my screen. Anyone know the cause of it?

Total shot in the dark, but does disabling Object-Object Occlusion fix it?  This is usually a Mac thing.
Activate the Develop menu in the top menu bar with CTRL+ALT+Q, Develop -> Rendering -> Object-Object Occlusion.
If that doesn't help, enable OOO again as it helps with performance.

If this doesn't  help, in the top menu bar of the viewer, go to Help -> About Firestorm.
