--- Comment #4 from steckdenis@yahoo.fr 2010-09-27 02:12:38 PDT --- 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.

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

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).

Those who reported issues on other GPUs should file separate bugs.
