(In reply to comment #7)

Does it help if the width and height of the background image are powers of two?
Some hardware can't directly accelerate repeating blits otherwise. With xserver
master (to become 1.5) exaFillRegionTiled() could be used instead, but that may
not be very efficient yet either with small patterns.

Also, as mentioned in comment #1, when I profiled blogger.com earlier, at least
with Firefox the problem seemed mostly related to stippled fills, not
compositing, so I'm not sure this is really (still) the same problem. Can you
provide your profiling data?
