Mike,

thanks for the tip. It did help. A little update: it helps if you just turn off Aero, not return to WinClassic theme. Win7 Basic will do away with the flicker too.

You only have to restart Premiere for anything to happen. (At least that was the case with me).

Best,
Natasa

I think it has something to do with display drivers.

I encountered the same problem after upgrading to win7 x64, with Q6600 CPU and Nvidia 8800GT.

Since Nvidia doesn’t have 64-bit support for the GPU, I researched a bit and found CUDA drivers, which solved the GPU instability problem.

The flicker didn’t go away with CUDA drivers. However, while I was installing and uninstalling different drivers, to find the best one to work with, I discovered that when the system runs without ANY display driver there’s no zoom bar flicker in CS4. The playback is sluggish and it’s of course impossible to work in it, but zoom bar doesn’t flicker. Thus, I believe the flicker comes from the not yet appropriate display driver support for 64bit OS.

So, if I’m guessing well, we’ll all have to wait for our GPU manufacturers to come out with the appropriate 64-bit drivers for our cards.

I’ll keep you posted on the issue and please you do the same.
