Hi.

GTK+-2.18 introduced client-side windows, which means that not all
GdkWindows are now backed with native window. The only GdkWindow that
is always backed by native window is applicaition's toplevel window.

This probably explains why your drawing would end-up on the toplevel.
It is possible to set GDK_NATIVE_WINDOWS env variable, in which case
all GdkWindows will be native windows like in GTK+>2.18.
