No. The problem I was fixing is that when you have a true transparent
application, it uses an ARGB visual. Then the frame would inherit that
visual and the gdk_pixbuf_xlib routines used to paint the frame would
clobber the Alpha bits to 00 - making the frame elements transparent.

I just tried 1.3.3 and the problem did not appear - so it seems like
something somewhere else has fixed it. Good news, I think :-)
