I would guess one of two things is happening then (under E):

        - you're doing a wire-frame (outline) move, so no
          window redraws happen
          I don't think this is what you are describing.

        - E is doing a window grab, letting you slide around
          a view of the grab, _then_ moving the real window
          when you let go of the mouse (probably withdrawing the window
          during the move so you see only the grab

With FVWM's opaque move the window sees all the intermediate positions and
does nots of redrawing if it's transparent.

One test (under E) would be to move a busy window.
Eg put up a plain xterm with

        while sleep 1; do date; done

Running in it, see it scroll. Now grab the window and move it around.
Does the scrolling cease during the move? The I suspect my second hypothesis
above.

Truly, the ultimate demonstration of the computer's utility is that it
continues to be indispensable in spite of those who run the things.
