--- Comment #1 from Chris Wales chris@chrobis.com 2008-07-16 04:41:10 --- Still present in 1.1.1 - I have however observed (I have an nVidia card) that loading the nvidia-settings program up immediately corrects the excess gamma; nothing else short of an X restart seems to do this. I have yet to locate this bug in any other games or demos.
