So I just installed PS CS4 as downloaded from Adobe's website. When I resize a window, the gray area in the background becomes totally corrupt. Doesn't affect the document itself but it's distracting. Looked around but didn't see anything about this issue... anyone else experienced this? I tried turning off OpenGL drawing in the Preferences but that didn't help. I've not seen any visual corruption anywhere else in OS X but wonder if it's a problem with the ATI 3870 at all. Never saw anything like this with CS2 or CS3. Edit: ack, it is OpenGL drawing. It wasn't obvious I had to restart Photoshop for it to take effect. Still, an annoying bug. Anyone else seen this?
