Summary: Regression in x11drv due to
                    http://cvs.winehq.com/patch.py?id=6301
           Product: Wine
           Version: CVS
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: wine-x11driver
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

The patch http://cvs.winehq.com/patch.py?id=6301 introduced a regression:
with "DesktopDoubleBuffered" = "N" and "ScreenDepth" = "8" in the config file
wine get's a SIGSEGV, tries to start the debugger, next SIGSEGV looping forever.
Setting "DesktopDoubleBuffered" = "Y" or commenting out "ScreenDepth" (or
setting it to 16) makes the bug go away.
The SIGSEGV happens in DefaultScreenOfDisplay (X function) called from
X11DRV_GDI_Initialize and that one is called by process_attach (x11drv_main.c) .
