             Bug #: 31978
           Summary: LWA_COLORKEY support significantly slows down GOG
                    installer verification progress bar
           Product: Wine
           Version: 1.5.15
          Platform: x86
        OS/Version: Mac OS X
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: winex11.drv
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: jonas.bugzilla at gmail.com
    Classification: Unclassified


Installers from gog.com always first verify their own integrity. During this
period they display a custom progress bar, which makes use of the LWA_COLORKEY
attribute.

Prior to wine containing support for LWA_COLORKEY, this verification process
was basically limited by the speed of the hard drive. Since that support has
been added, the verification has become much slower, and furthermore the
progress bar flickers a lot.

I've bisected the cause to

    winex11: Add support for the LWA_COLORKEY layered window attribute.

To reproduce: it should happen with any installer downloaded from gog.com. I
tested with the freely available http://www.gog.com/en/gamecard/teenagent

I'm using XQuartz 2.7.4 on Mac OS X 10.6.8. If you need any traces, let me know
