Uh, I don't think they are the same. This one looks like it affects
only gnus; everything else in emacs seems to work fine. It was very
confusing when it showed up, and my initial bug report wasn't exactly
well written. So I looked at #13864 and tried to reproduce it in this
context. Looking closer at what I reported about showed the behaviour I
tried to describe, hoping some more detailed info might make it easier
for you to look into it.
#13864, Lars' observations and what I'm seeing here /could/ all be
related since it all has something to do with the display, but I
wouldn't be able to tell.
