           Summary: Lineage2 C4 doesn't work approx since 0.9.19-20
           Product: Wine
           Version: 0.9.30.
          Platform: Other
        OS/Version: other
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-directx-d3d
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: mills at rambler.ru


It show internal window with message "directx error ..." soon after creating window.

As I see in attached backtrace problem is in
IWineD3DDeviceImpl_DrawIndexedPrimitive function from wined3d\device.c

With the following patch that error window gone and application started.
There was no goal to find out why pIndexData was not filled with non-NULL value
in that case. So there is still bug somewhere and patch is only workaround.
Goal was just to run game on recent wine and not on 0.9.18.
