Yes, please provide more details.  We are very interested, as we are
close to releasing Emacs 25.1, of which 25.0.95 is the latest
pretest.  What you told so far is disturbing, but doesn't give any
clues where to look for the root cause of the trouble.  I don't think
we've heard such reports in a long, long time.

One idea I do have is to build without --with-cairo, and see if the
problem goes away.  The Cairo back-end is still experimental, and we
know of several problems with it.

Thanks.
