It doesn't improve anything, but it changed something: now the five-pointed
star looks like a square; the new screenshot called "same star, with patch"
shows the exact same white star from the other screenshots, as it looks with
the patch applied

Actually, I realised I loaded the wrong saved game; that square wasn't the same
star from the previous screenshots (sorry for the confusion).

In sum, the patch changed nothing at all. As before, all textures in the game
look tiled, like a jigsaw puzzle (problem with texture coordinates, perhaps?
putting pieces of the texture in the wrong places?)

Does disabling colortiling help?
Option "ColorTiling" "False"
in the device section of your xorg.conf

I've committed a workaround, could you try current mesa git?
