I've been having a problem with the camera COF in AE CS4 for a few days now and it causing big problem with my ability to work.
Basically a strange grainy/pixelated strip appears across my composition when I turn on the DOF. It is happening in every single project I have, even if I just set up a simple project that has only one 3D solid layer and a camera. It is there in the preview and the final render. If I adjust the DOF setting it moves the strip around a bit and makes it thicker and thinner but it never goes away.
I've had a few suggestions so far including turning off open GL, reseting preferences, and getting the latest updates, but none of these have helped.
If anyone has any idea what might be causing this and an solutions it'd be much appreciated.
I've attached a screen shot, the weird strip can be seen best on the right side of the composition, it's faint but very annoying.
