A small update for those who might have the same issue at some point:
The game files and config doesn't factor into this issue much:
Forcing Anisotropic Filtering appears to "repair" the interface (maybe it aligns the driver more with what Ryzom expects).
Font blurring is another matter, tho, and Aero doesn't seem to have anything to do with it for once.
Morphological Filtering, Edge Detect and Supersampling Anti-Aliasing all screw with text sharpness, so I recommend normal Multi-Sampling.
