Bug ID: 44364
           Summary: Wincfg does not save graphics preferences
           Product: Wine
           Version: 2.6
          Hardware: x86
                OS: Mac OS X
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]

When using wine 2.6 under MacOS 10.12.6 (Sierra), when opening winecfg and
trying to change the settings under the graphics tab, it is not saved upon
apply->OK.

The changes made were

"Emulate a virtual desktop" -> YES
"Desktop size" -> 2560x1440

This is required to prevent wine from using two monitors (the secondary monitor
is just blacked out) when trying to run full screen applications (mostly
games).

I understand that wine 2.6 does not keep a ~/.wine configuration directory but
rather uses registry settings but I can't find the required keys in regedit and
I can't find where it is set by looking through the source:
https://github.com/wine-mirror/wine/blob/master/programs/winecfg/x11drvdlg.c

Please let me know if I'm missing anything or if this is intended behavior.

Thanks.
