           Summary: Wine 0.9.20 breaks Everquest 2
           Product: Wine
           Version: 0.9.20.
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-directx-d3d
        AssignedTo: wine-bugs(a)winehq.org
        ReportedBy: wine(a)kapila.force9.co.uk


Wine 0.9.19 allowed Everquest 2 to run as far as entering the 3d part of the
game (ie putting a character in the world) at which point there was a crash in
the EverQuest2.exe 

However it looks like 0.9.20 has broken this so that you cannot get that far.

When running normally,  you get back ground music, and about 3 full screen
images are displayed, followed by a login prompt.  With 9.20, you only get a
black screen. (music still plays.)

Replacing the wined3d.dll.so with the 0.9.19 version allows it to work again, so
it appears that something in the 0.9.20 build of this dll is causing the problem.

So far it appears the issue was not introduced by changes to directx.c or
surface.c so it must be in one of

 dlls/wined3d/arb_program_shader.c 
 dlls/wined3d/device.c             
 dlls/wined3d/drawprim.c          
 dlls/wined3d/glsl_shader.c        
 dlls/wined3d/stateblock.c
