Edzard has already responded with what's probbly the right answer, i.e. to make sure you use a BOX rather than a FRAME type for your main window, and then callaing main_win->redraw(); should have the desired effect.

That is more or less back-to-front... What clear_damage() does (in hand-waving terms) is clear the (internal) flags that allow the renderer to know that a widget (e.g. the window in this case) has been damaged and needs to be redrawn. So by *clearing* the damage flags, you are telling the renderer that no redraws are needed - Which ties in with what you see, I think. What you need to be doing is *setting* the damage flags - which is what win->redraw() does anyway...
