We see this with lighting enabled. With lighting disabled, correct colors and
transparency return.

No. We see lighting broken as described in your first paragraph.

We here at MultiGen have reproduced these problems using both SmartScene and
perfly. The performer_eoe.compat subsytem DSO's, as shipped with Performer 2.2,
are BROKEN as described above. They are unusable.
A simple test is simply to run perfly with no command line arguments. The "Iris
Performer" text on the opening screen is the wrong color (greyish).
Regards.
