http://bugs.winehq.org/show_bug.cgi?id=20411

Summary: X11DRV_AlphaBlend not a dibsection
           Product: Wine
           Version: 1.1.31
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: gdi32
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

Starting a sector of AtcWindows with the option "Transparent Supplementary
Dialogs" checked, prints the following message on the console:
fixme:xrender:X11DRV_AlphaBlend not a dibsection

The transparent message box (for the communication) is not displayed (as is
should) thus leaving you with no initial calls and read backs from the
aircrafts (making controlling the aircrafts impossible).
