This latest patch (v4) certainly works with Aliens versus Predator Classic
2000. The game this issue was first reported against.

The latest patch also appears to be pretty robust. I can't think of any corner
cases that would break it.

It would be nice to see the patch land in Wine 4.0 - since it affects a lot of
games. The issue is technically a regression. Since it was introduced when the
Virtual Desktop panel window was forced as topmost:

SetWindowPos( tray_window, HWND_TOPMOST, 0, GetSystemMetrics( SM_CYSCREEN ) -
tray_height,
                  tray_width, tray_height, SWP_NOACTIVATE | SWP_SHOWWINDOW );

with Wine 1.9.11.
