I've always had the same effect (g3/beige, atyfb, mach 64 3DU_pro, 0x4750,
rev 0x5c).  I was hoping XF4 might fix it... ah well.

FWIW I never got any answer to a post ages ago about this.

This has occurred on all kernels I've tried 2.2.6 ... 2.4.2 and
{XF3.3.5/3.3.6, Xpmac rev6 ... rev 11) - so I guess, by process of
elimination with the other posting, it's in atyfb - or the hardware...
