Dunno whether this is pertinent to this thread. If not, ignore.

It just happened for me that (a) I was in an Emacs (recent build)
buffer/frame and then (b) I clicked a non-Emacs window mgr window.
(Neither the Emacs frame nor the other window-mgr window obscured
the other.  They were just next to each other on the screen,
without overlapping.)

The Emacs frame display immediately turned blank - lost *all*
display of the text etc.  I clicked back in the Emacs frame - still
nothing displayed.  I hit `C-l', and only a little bit of the text
was then displayed.

This didn't happen previously, AFAIK.  (I naively get the
impression that someone has being trying too hard to skip some
redisplaying, in an attempt to optimize things.  Too clever by
half, perhaps?)

Again, if not helpful at all, please ignore.
