Thanks.

Once again, the traces of handling the expose event are identical
between the "good" and the "bad" cases.

I have only one more idea: can you build Emacs without Cairo?  Cairo
changes the way Emacs draws the screen in significant ways, and that
is the only part of this puzzle that we didn't verify yet.  The traces
indicate that everything up to the point where we invoke the drawing
code is identical between the "good" and the "bad" cases, and
correctly instructs the display back-end to redraw every screen line
in the exposed region(s).
