I also see the corrupted ground on both rv670 and rv790.

Running d-r-t kernel I haven't seen any other corruption yet.

Starting in spectator mode the ground is OK until moving around, when
patches/strips become corrupted.
It is possible for corrupted ground to become normal again when viewed from a
different place.

I have tested with the above settings disabled and with various in game
settings - it makes no difference.
