wxgui: refreshing display after erasing displayed map creates encoding error

[mlennert]

When I display a map, then erase it and then refresh the display, I get the following encoding error with a fresh trunk:

Yes, you're right. That seems to be exactly the same thing. Closing this one as duplicate of #3517.
