I'm under fvwm here, debiqn testing. Starting with a big image (let's say 800x800) and a window size of 100x100, the Expose event handler does not display anything. Things start to work when I resize the window. If the new width or height is > 800 (I didn't check the exact limit, something bigger than source image) then Expose works fine.
