--- Comment #38 from knan-wine@anduin.net 2009-02-22 11:00:17 --- Created an attachment (id=19608) --> (http://bugs.winehq.org/attachment.cgi?id=19608) screenshot w/return &ffp_fragment_pipeline
(Without debug hack, only with the return &ffp_fragment_pipeline hack suggested)
Those clear strips must be the game/graphics being mid-update, I didn't see any clear strips in-game.
