           Summary: Retina Mode broken since
                    7f7f9fa22c5cbe629e79a54257d5bd21403e80db
           Product: Wine
           Version: 7.9
          Hardware: x86-64
                OS: Mac OS X
            Status: NEW
          Severity: normal
          Priority: P2

create_original_display_mode_descriptor.

A quick check suggests that the registry key itself is picked up OK, so the
problem is probably that the retina code doesn't see the original display mode
correctly and thinks the mode has been changed.
