I see only 6 screen lines (including the menu bar) being redrawn.  Did
you show only part of the refresh?

Anyway, the important thing is to understand why the enabled_p flag of
these screen lines is reset, because all those calls to write_glyphs
that you show are due to that cause.  That is what causes Emacs to
redraw these lines, even though they are actually unchanged.
