Ultima IX: Ascension - dark text and missing intros

[WinterSnowfall]

Rendering seems fine except for the subtitles/text, which show up as dark characters, almost invisible to the surroundings. Intro playback is also problematic, only showing a black screen.

Apparently the missing/dark text also happens with WineD3D, so it's most likely a Wine bug, unrelated to rendering. Even the missing intros reproduce with WineD3D.
