A few pictures of what I'm seeing are attached.
Environment: Linux kernel (Linus' current git with s3tc support) libdrm, xf86-video-ati, mesa @ current git
RV770 [Radeon HD 4850] [ 153.910] (II) RADEON(0): KMS Color Tiling: enabled [ 153.910] (II) RADEON(0): KMS Pageflipping: enabled [ 153.910] (II) RADEON(0): SwapBuffers wait for vsync: enabled
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.
