3D and XY grid window does not refresh with "lighter" window managers.

[hamiltond]

It works with gnome and kde. It does not work with awesome, xfce4, windowmaker, etc.

Simptoms:

• Although the application works, i.e. it is possible to draw a rectangle in the xy window but the rectangle becomes visible only after resizing the whole application.
• When alt tabbing back from a different application (say firefox) a residual image remains in place of xy window. (only tested in awesome)
• When resizing the xy window imprints of the resize-bar (?) remain all over the app.

This is most likely a problem of gtk2 and/or gtkglext not getting or catching events.

Does it still happen with newer GTKR? 1.6.5/.6 ?
