Summary: Need DIB engine - Unnormal slowness in Arx Fatalis
           Product: Wine
           Version: 0.9.24.
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: P2
         Component: wine-x11driver
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

I decided to create this bug, since bug 3902 is resolved. 
The fps in the game Arx Fatalis drops dramatically in the game menus, and ingame
under certain circumstances, this is most likely due to the lack of a DIB
engine, as bug 3902.
The patch which solved bug 3902 doesn't seem to take into account the kind of
structure which is used in arx fatalis. I don't know much about it, but looking
at the code, the patch seems to check for this kind of dib, and discard it, as
it cannot handle it.
The wine output is filled with :
"fixme:bitblt:X11DRV_ClientSideDIBCopy potential optimization: client-side
compressed DIB copy"
