I'm fairly certain the program doesn't make the slightest attempt to guess anything at all about decorations, the shift on each start is exactly the window decoration dimension. My current kludgery of modifying the saved calibre gui position works fine, but I'm pretty sure to get a fvwm only solution, I'd have to do something like explicitly move the window after an initial timeout, which would be more trouble to figure out than the nonsense I currently use :-).
