Does this make any difference? In

Hello,
I also encounter this bug and investigated it. When I launch Neverball, the
first frames are displayed ok. Then they slowly begin to disappear, each frame
having less content that the previous.
I restarted Neverball and quickly clicked on the Play button, and I played the
first level.
It seems that the Z buffer is not cleared between the frames. I can see the
level when it comes nearer to me, but when I play it, it disappears. The only
thing I can do is to tilt the ground as much as I can, to make it nearer to the
camera.
I looked at the code, but didn't find when the Z buffer is cleared.
I use Linux 2.6.36-rc3, Mesa Git (2010-09-27), libdrm 2010-08-24, Xorg Server
1.9, xf86-video-ati 6.13.1, on a RS690 card (ATI Radeon X1270) with 128Mb of
sideport memory.
I tried the proposed patch, but it didn't worked.

I can confirm that (it's not perfectly visible on glxgears)

Review of attachment 42432:
--> (https://bugs.freedesktop.org/review?bug=29851&attachment=42432)
This patch fixes HyperZ corruption in Unigine Sanctuary and Scorched3D for me
(RV530) and decreases amount of corruption in Lightsmark. Also no regressions
encountered so far with other games tested (HoN, SC2, War3, Osmos).

Commit d1dbbf7bf41959df489195d11eb50f8222d293d3 disables hyper-z on rs6xx+, it
seems the hw can't do it.
