screenshot of misplaced menu entry

In wine 10.0-rc6, when using two monitors with the *right* one set as primary,
the menus are now misplaced, e.g. when opening a menu entry in a window on the
left monitor, then it opens offset by the monitor size to the right, on the
primary monitor, as shown in the attached screenshot.
When the window is on the right monitor that continues, so the menus are not
shown, since they are likely drawn off screen.

Setting the left monitor as primary fixes this as a workaround.

Also, it only happens on X11 / XWayland (not with the wayland driver, where
menu positioning now works correctly)
