When hyperz is enabled, I get (apart from the stencil related errors) some
blue flashes with the old order (look exactly the same as without hyperz and
the new order), and a lot more flashes with the new order. Hmmm...


with the current radeon driver I get flashes in nwn on characters in
certain scenes, I'm actually playing it at the moment, but I don't have my
second machine available for a couple of weeks to debug it :-(

With radeon, only on the characters? This is likely caused by the "environment mapping on creatures" which uses GL_SPHERE_MAP texgen and causes a tcl fallback (and those don't quite work correctly) on both radeon and r200 currently. Switching it off should get rid of that, though you also need to turn down texture detail to lowest, otherwise it looks the game ignores this setting for some reason. At least it helps on rv250 (another solution for rv250 is to just not do a fallback, I guess that's not an option on radeon...).
