--- Comment #3 from Robin Watts <robin.watts at artifex.com> 2011-01-19 18:04:10 UTC ---
Fixed in revision 12038.

The code contains an optimisation to allow us to spot the case where strokes
are being rendered solid with a normal blend mode, and to allow us to use the
fast path through the code. In this case we were using "compatible" blend mode,
which is supposed to be the same as normal, but wasn't triggering the fast
code.

The fix is simply to map "Compatible" -> "Normal" within the code.
