Since this is on a PowerBook without mmx, the problem would have to be
with the optimization for 1x1 repeating pictures. The only bug I could
see in the code for that it would incorrectly turn off repeating for
1xn and nx1 pictures.

I have fixed that now and rewritten it to be less convoluted, so the
bug may be fixed now, although it would surprise me if ClearLooks
actually uses 1xn or nx1 pictures.

This should be fixed in a different way now.
