This is consistent with what you reported earlier, namely

  Bad configuration (both VGA1 and LVDS1 enabled):

  (window-height) ==> 34
  (window-pixel-height) ==> 613

This is not consistent with what you reported earlier, namely

  Good configuration (only VGA1 enabled):

  (window-height) => 34
  (window-pixel-height) => 612

Can you try getting the results of `window--dump-frame' for these old
(good and bad) configurations, that is with the build you used in your
initial report?  I'd want to see different pixel heights (not 669) for
these two frames but can't tell anything unless the pixel height (612)
of the good window reemerges.

So try first to get the different (window-pixel-height) values back and
then evaluate (window--dump-frame) instead of (window-pixel-height).

Thanks, martin
