What you could try is to extend getNonStrokingPaint and getStrokingPaint
and set both values to 1 (that is the default if no ca/CA entry exists)
with setAlphaConstant() and setNonStrokeAlphaConstant().
If that doesn't work, then modify the PDF by going through the page
resources recursively and change the ExtGState objects.
(resources.getExtGStateNames() and resources.getExtGState). Do this also
for form XObjects (and more).

That seems to be the culprit, thanks!
We worked together in the past to coerce documents into never
rasterizing... the fix we had originally written a workaround to
removing transparent layers.

I understand that this is slightly off-topic, but can additional
logical improvements be made to that logic to help with scenarios like
this? Assuming the answer is yes, should I start a new email thread
(or bug report) about this?
In regards to the originating issue (the second page), I'll re-test
with the "CA 1" entry removed.
