[Bug 23250] New: Twinview - wine only launches if desktop size is smaller than actual screen resolution

http://bugs.winehq.org/show_bug.cgi?id=23250

Summary: Twinview - wine only launches if desktop size is
                    smaller than actual screen resolution
           Product: Wine
           Version: 1.2-rc3
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

When running twinview, Wine prefers the left desktop to start on for
full-screen apps. For windowed apps, the resolution must be set to 1 less
vertical pixel than the actual resolution (1280x799 on a 1280x800 screen) for
the Wine app to start on the correct desktop (from which it was launched).

This may be related to http://bugs.winehq.org/show_bug.cgi?id=18833, but I
believe more clearly indicates some underlying cause. Posted a forum thread
about it here http://forum.winehq.org/viewtopic.php?t=8664.

As far as I can see, Wine is trying to do this:-
1. Start app on screen its launched on (correct behaviour)
2. Unable to do that if window size is exactly same as screen (wrong behaviour)
3. Prefers left-most window (0x0 position I guess) if 2. fails (correct
behaviour)

This is on Gnome, running compiz or metacity (no difference in behaviour).
