Hello there I have the following issue.

I passed from debian sid (mesa 7.7) to ubuntu 10.10 64bit (mesa 7.9dev)
I own a Vaio TT with an integrated intel card.

direct rendering: Yes
server glx vendor string: SGI
server glx version string: 1.4
server glx extensions:
client glx vendor string: Mesa Project and SGI
client glx version string: 1.4
client glx extensions:
OpenGL vendor string: Tungsten Graphics, Inc
OpenGL renderer string: Mesa DRI Mobile Intel® GM45 Express Chipset GEM 20100330 DEVELOPMENT 
OpenGL version string: 2.1 Mesa 7.9-devel
OpenGL shading language version string: 1.20
OpenGL extensions:
    GL_3DFX_texture_compression_FXT1, GL_APPLE_client_storage, 
00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)
Linux teo-vaio 2.6.35-22-generic #33-Ubuntu SMP Sun Sep 19 20:32:27 UTC 2010 x86_64 GNU/Linux

Here a photo of the bug to clearly show that all the animations became invisible:

I never had any issues since the game went out, so I guess there has been a regression or a bug in the latest versions of mesa (also the 7.10 git has the same issue).

I already tried to reinstall ubuntu, reinstall the game, update the kernel, the intel driver and mesa to the latest version available, all without success.
I hope you can understand what this bug is.
Regards
