I recalled seeing this bug on a friends PC back in 1999 and wondered what was up with it. The guy had issues with Neriak rendering the neon glyphs on the wall correctly and yeah, he was able to see a model for the Enchanter animation pet as seen above.
The card he used was the old Creative Labs 3D Banshee card using the stock driver. In an update that was issued a couple of weeks later, the new driver removed the bugs.
