Oh, FuzzyQ, let me stress, there's no matter for apology, and this is
not a 'go away' message at all.  The clarity of a tightly-defined bug
case is a good thing.  Bug 938658 as it grew here built up a very
specific definition.   That's nice when you can get it, and the
narrowly-defined case seems to have been addressed.  As evidence, me and
Shayne's great minds apparently posted about this, around the same time.
;-)

Certainly related, I agree.  There have been a number of bugs with blank
windows (all on nvidia?  I'm not sure).  There were separate reports,
even after duplicate-marking, for minimized windows just showing blank
in the spread view.  And clearly there are ongoing problems.

If we can say:

  OK: maximize->minimize->restore is no longer a guarantee of a blank window.
  Now, what problem cases remain?  Just how are they defined and reproduced?

it helps manage the complexity.

Your friendly postings here are a fine way to compare your current
symptoms to others'.  From your helpful descriptions, the definition of
those problems sounds a little different, than the set here that seem
fixed.   If so, we can wipe this one off the chalkboard, and get a clean
slate for work on the next one.  The underlying connections will be
clearer to those who know the code, as I don't.

By 'we' in that sentence, I have to mean the community in general, but
if you find a recipe where I can start to reproduce these symptoms, I
will certainly subscribe to that bug, too.  In this case, I'll say, go
ahead and subscribe me to your bug, if you'd like, whether you find one
or start one.  I couldn't write it up, myself, 'cause I can't observe
it, yet.

Finally, I speak with no authority here; this is just how these things
usually work best, from my experience so far.  This is my
recommendation, for the best path to fixin' the problems you're seeing,
not to buzz off.  You don't have to buy it, either way.

And now I hope I have buried any seeming negativity in a flurry of
words, and perhaps droned you into a comforting slumber.  :-/
