Menus drawn under vte windows on Intel graphics with multiple displays

[Victor J. Orlikowski]

This bug is somewhat "odd."
Using an Atom N280 netbook, Intel graphics.

With any of: gnome-terminal, xfce4-terminal, or roxterm.

If I connect an external display and (using arandr) enable it with the display being positioned to either
the "right" of the (primary) LVDS display or "above" the LVDS display, menus selected from the menu bar are drawn *beneath* the contents of the terminal window.

This *also* occurs with right-click context menus (which is how I discovered that the menus were being drawn beneath the window, rather than not being drawn at all).
