Close this bug if you feel like it.  This is only to say that since a
few months ago (?) Emacs redisplay seems to be broken.  I do not have a
recipe, but I would be surprised if no one else sees this at all.

If I create a new frame (e.g. C-x 5 f) that partially obscures an
existing frame, for instance, and the select that partially obscured
frame (e.g., by clicking its title bar), so that it is raised again, the
part of the buffer that was obscured looks wiped out (blank).  And
repeated C-l does not fix this.  My workaround is to thumbify and then
dethumbify the frame.  (Probably iconifying and deiconifying would work
too, but I do not iconify anymore.)

This does not happen systematically - just sometimes.

Again, feel free to close this for its lack of reproducible recipe.
Just wanted to give you a heads-up that redisplay is somewhat broken
now.
