Black Screen with ATI Graphics Cards

If you have this issue, we would be very grateful if you could help us try to isolate the cause.

Here are some work-arounds to solve the problem:

• disable Render Glow in Preferences → Graphics -> Rendering
• disable Vig. Amount in top menu, World → Photo & Video → Phototools -> Gen. (if Advanced Lighting Model is enabled in Preferences → Graphics → General)
• disable Basic Shaders in Preferences → Graphics -> General

Windows: Installing the Catalyst 12.01 driver (which may imply reverting to an older version than you currently have) is likely a preferable solution; links are provided here.

Mac: The issue has only been seen on Snow Leopard (OSX 10.6.8) so far. Since drivers are tied into the operating system on Macs, you would need to upgrade to Mountain Lion (OSX 10.8.3) for a permanent solution at this time. If that is not an option for you, then use the workarounds above.
