Bug #: 33396
           Summary: GetSystemMetrics always reports native resolution with
                    --with-xinerama.
           Product: Wine
           Version: 1.5.28
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: winex11.drv
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]
    Classification: Unclassified

As the summary says, GetSystemMetrics(SM_C{X,Y}SCREEN) always reports the
native resolution, even if an application changes the resolution, unless I
configure Wine with the --without-xinerama option. This can be seen when I run
D3D9 device tests, leading to test failures (see attachments).

I am on the NVIDIA proprietary driver version 313.18, which may be relevant as
this driver does have the "broken" XRandR 1.2. I cannot test with Nouveau
because it doesn't support my GPU.

Even if this is the proprietary driver's fault, I'm still opening this bug on
the WineHQ Bugzilla to track its resolution here, and provide information to
the NVIDIA developers if we do have to report it to them.
