--- Comment #23 from Piero Finizio <andabata12 at yahoo.it> ---
Bisecting is  difficult because almost every day I compile from git but i
change mesa/drm and xorg/driver/xf86-video-ati in ensemble...
Plus  I compiled on Fedora 18 with 3.7.x-xx kernel that carries power
management improvements and other work for the Radeon driver.

To get rid of bug I reverted the commits:

r300_screen.c

- case PIPE_CAP_DEPTH_CLIP_DISABLE: /* XXX implemented, but breaks Regnum
Online */
return 1;
...
case PIPE_CAP_INDEP_BLEND_FUNC:
+ case PIPE_CAP_DEPTH_CLIP_DISABLE:

------------------

r300_state.c

- R300_PS_UCP_MODE_CLIP_AS_TRIFAN |
- (state->depth_clip ? 0 : R300_CLIP_DISABLE);

+ R300_PS_UCP_MODE_CLIP_AS_TRIFAN;

----------------- 

now i dont need anymore this way and the version of Second Life viewer is the
same: CoolVLViewer-1.26.4.48-Linux

Another path of investigation would be the anti-aliasing performance
optimizations By Marek Olsek.
Anyway I will try to help within the limits of possibility.
