It should be relate to fbc, try to disable it and test again.
I disabled FBC by adding line Option "FramebufferCompression" "false"
The bug still exists.
In Q965, the bug does not exist.
with fbc disabled, rendercheck can pass on my box.
fbc on G965 is default off, so this shouldn't be a problem for now.
check you with latest intel driver.
I'm a little confused by this one, the subject says the bug appears on 965GM, but the initial post says G965.
Framebuffer compression is only available on mobile parts, so regardless of whether "FramebufferCompression" is "true" or "false", it'll only be enabled on e.g. 965GM or 915GM, not 965G, 965Q or other desktop parts.
So if the problem exists on non-mobile chips, it's probably just a generic rendering bug.
The initial G965 is a typo.
I will test again with latest driver on T61.
Now rendercheck passed on 965GM with FBC.
