Description Pavel Ondračka 2013-05-19 20:37:51 UTC 
Shadows are flickering in Legend of Grimrock. Its quite noticeable in the game, however not very visible in screenshots. I was quite sure it worked some time ago so i did a bisect and this showed up:

456dbcc3377ee23dbeffa4da02a4d80a8519bb62 is the first bad commit

    i965/fs: Before reg alloc, schedule instructions to reduce live ranges.

The game doesn't have a demo, however i can make an apitrace or provide any other information if needed.
