--- Comment #9 from MD.IMAM HOSSAIN imamdxl8805@gmail.com 2011-06-09 20:10:22 CDT --- I think it is not a WINE's problem if other drivers is not experiencing same problem.
We need to file another bug to https://bugs.freedesktop.org
https://bugs.freedesktop.org/show_bug.cgi?id=35373 is fixed but games are a bit brighter but not completely normal.
