Shadows in Doom 3 are broken (see screenshot). This is a recent regression so I will try a bisect later.

-- Machine or mobo model: Asus P5Q-EM
-- Display connector: DVI
-- KMS: enabled

Comment 1 Sven Arvidsson 2009-09-11 15:10:31 UTC
Bisect leads to this:

f5539b6991e336aa1cf302dbdb1a29b3e85cff36 is first bad commit

Apologies! The first bisect was wrong, this should be it:

50d8b295f6c950da3b8783ff6e1803bdfbb5c7cc is first bad commit

    intel: use _mesa_meta_clear(), it's a bit faster

Bug 23857 is also about a regression caused by the same commit.
