When the making a multipage plot with a non-zero rotation (plsori(1) is needed in eps for correct orientation in xfig), labels and annotations are missing from all but the central subpage (assuming there is one). I think this is most likely caused by either the clipping box for text or the text transform not being correctly rotated.
The attached code will demonstrate the problem for the epsqt driver.
The problem occurs with all the qt family drivers I have tested.
The problem does not occur with the cairo family drivers.
