             Bug #: 30299
           Summary: Graphical glitches AMD/ATI graphic cards in some
                    specific games.
           Product: Wine
           Version: 1.5.0
          Platform: x86
        OS/Version: Mac OS X
            Status: UNCONFIRMED
          Severity: major
          Priority: P2
         Component: -unknown
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: paulthetall at gmail.com
    Classification: Unclassified


There are a list of games which do work fine on the Mac with Nvidia graphical
Cards, but give massive graphical glitches on AMD/ATI graphical Cards. Examples
of games which are infected with the issue:

Red Faction Guerilla
Tombraider Underworld
Assassin Creed
Lara croft and the guardian of Light 
Crysis 2
The saboteur
Lord of the Rings War of the North
The adventures of Tintin
and quite some others which are infected 

UseGLSL=disabled does not work in those cases and also changing display
settings in the game (like shadows and such which might sometimes help in other
games with other graphhical glitches). So this passes that part.

There is a demo for Lara croft and the guardian of light which you can download
to test http://store.steampowered.com/app/35130/

Linux users probably won't have this issue becasue they can install graphical
driver updates from the Graphical card developers. Apple on the otherhand have
not that luxury and we are stuck and dependent on apple updates. However
somehow Transgaming with his Cider wrappers which is mostly wine overrulled
this issue for AMD Radeon/ATI cards. So it is possible to run this kinda games
on the Mac. Most likely because Chris bently from AMD Supported Cider so it
might be they give some fixes for this kinda issues to Cider which they used to
get it run properly for AMD Radeon card Macs.

So to you guys the question to look into it. You can use the deo te reproduce
it on an AMD/ATI Mac to get the right debugcode. Also I made a video which
shows the graphical glitches i talk about up here:
