That sounds weird, can you create screenshots or something to illustrate
the problem?

This is most likely due to the coordinate limits of the hardware 3D
engine. That could be worked around in the Mesa driver, but there would
still be the texture size limit others pointed out, and that can't be
worked around in the drivers with the current
GLX_EXT_texture_from_pixmap API so it would have to worked around by
different means by compiz.

I've seen this before, I think it happened
when /apps/compiz/general/allscreens/options/texture_filter is set to 2
(maybe also 1)
and /apps/compiz/plugins/cube/screen0/options/inactive_opacity was set
to less than 100 (which I think is a bad idea in general).
