This built-in gspca webcam is the only one I've had problems with. The
more expensive Logitech ones always worked fine for me.

The laptop just got a fresh F19 install. I just wiggled the webcam after
starting Cheese and to my astonishment the green led lit up and Cheese
showed something. The pic was very bad, interlaced and it seems to copy
everything 3 times horizontally while overlapping those images. I set it
to 320x240 and no change. So also in F19 at least my gspca webcam is not
working very well.

Understand. The only reason I suggested it is that if you figure out
which patch causes the issue that you could then file a BZ so that it
might get fixed.
