I’ve seen this in the older AlexP drivers as well as the new CodeLabs ones (currently using 4.0.1.0217 on Vista 64).

In the attached 320x240 capture, the alternating incorrect colors are particularly noticeable on the edges of black keys.

Has anyone else seen this problem before?

The artifacts you are seeing are due to the de-bayer process. Try increasing the resolution to 640x480.

It’s happening at 640x480 as well. Is it possible the camera is outputting a different filter pattern than the driver is expecting?

This screenshot also shows a potential problem with the auto gain setting (see the keyboard at the bottom right). If I set the gain manually, this clipping does not happen.
