Looking at it again this morning, it seems this depends only on the width of the captured frame. It always seems to happen for widths between 374 and 385, independent of the frame height, bits per pixel, or transfer address. Real easy to reproduce: "fxtv -geometry 384x345" No ideas jump to my mind on this one. Any thoughts? At first I thought it might have been a bandwidth limitation being exceeded, but observing the same wavy lines for the same frame width range in both 2Bpp and 3Bpp modes probably shoots that idea down.
