Bug #: 29611
           Summary: FL Studio 10 is invisible without "emulate virtual
                    desktop"
           Product: Wine
           Version: 1.3.37
          Platform: x86-64
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]
    Classification: Unclassified

When running FL Studio (version 10), the main application window is invisible.
To clarify: it's not that an empty window appears or something like that.
Instead, nothing appears except the initial pop-up dialog of FL Studio that
informs you that this is a demo. The only thing that's visible is the task
manager entry in KDE's task manager panel.

When enabling "Emulate a virtual desktop" in winecfg, then the application
shows up correctly.

I'm using Wine 1.3.37 on Gentoo Linux AMD64, using the Radeon graphics driver
(Gallium3D with KMS, Mesa 7.11.2 and also tried latest Git version.)

When trying to reproduce, you can download FL Studio from here:

It's a free download (224MB) and you don't need to sign-up or anything.
