Bad filtering on sharks

[Falz]

Finally got around to trying this screensaver. Runs great on my main box, but on my Voodoo5 machine the sharks are very shimmery - like they are being point filtered instead of bilinear. I suspect the screensaver is trying to set an invalid filtering mode (anisotropic perhaps?), and obviously most DX7 level cards don't support it, and it then falls back to using point filtering. Or it could be another issue all together I guess.
