Due to the stroke, I've not updated in a while.

The log shows:

GIT update -->
   repository:               git://git.sv.gnu.org/emacs.git
   updating from commit:     76f2d766ad6691eae6ae4006264f59724cc73a23
   to commit:                60ea900848ee03e1ccdba565220f589e0d8e72e9

After hitting the wrong key an having to restart, emacs came up
unwilling to show anything in the frame, once I used the WM to maximize,
which was not already part of the original frame.

OTOH, if I made the frame larger one row or column at a time (using the
mouse to drag the WM's edge decorations), it used the whole frame.

And it even re displays correctly after dragging another window over the
frame.

So it seems limited to frames which are resized quickly, such as via 
_NET_WM_STATE_MAXIMIZED_VERT and/or _NET_WM_STATE_MAXIMIZED_HORZ.
