bug#16684: Sometimes a frame is not drawn properly

[E Sabof]

I don't have a reproduction recipe for this bug, but here are some 
characteristics.

The cursor might not be drawn on the frame. Sometimes the frame may also appear 
"blank" - the background has the correct color, but there's nothing else. 
Changes are still displayed.

The behavior is identical in all windows of that frame, and creating new 
buffers or windows doesn't improve the situation. Everything becomes normal if 
I resize the window.

It usually occurs when I have been working with another frame on another 
virtual desktop, and switch back. I use xmonad which might handle some things 
differently from other window-managers.
