hi
that sounds familiar to me

are you using .emacs.desktop ?
cause i use it and i have two situations at times
yes i do use gnus wlust and mu4e

1) problems with monaco fonts overlapping as for bug 23360
temporarily solved by using xftfont.c from pretest 0.91
or a 2016-02-14 git clone i keep around

2) at times same 100 irresponsive cpu and swap loud grinding ;)
in a word : box completely freezes
i can only kill it from remote if i am already logged
otherwise i can only hard reset
yes : terrible bug

you are giving me some clues

that is something i am chasing from some time

to get my box alive i have to delete .emacs.desktop
so i wonder if you can do the same
and if we can blame  xftfont.c or something else

in my case the freezes start if i
ctrl right mouse popping the menu up
options -> set default fonts
to skip the the monaco fonts that as i said was overlapping

The -nw session doesn't use any font shaping engines, it uses text-mode stdio writes to the screen, so using it doesn't add any useful information about this problem. I believe Handa-san asked for "emacs -Q", not "emacs -nw". Can you try that?

Since we want to release Emacs 25.1 soon, I've added a variable, xft-font-ascent-descent-override, that allows to work around the problems reported in this and related bugs. By default, the variable is nil, which disables overriding the font ascent and descent values, as this seems to be unnecessary on most systems, and produces annoying results with some fonts. On those systems where the override is still needed, users can set the variable to a non-nil value to solve the rendering problems. With that, I consider the bug fixed for Emacs 25.1, and I'm removing it from the list of bugs that block the release. We would still want to find a proper fix for these problems, when their cause becomes known. Thanks.

I checked all the related files one by one. :-) I found thst the CPU 100% usage's cause is fontconfig. In my system, the fontconfig is 2.11.1. I reverted this to 2.10.2's fontconfig, then problem has disappeared! I wonder if the 2.11.1's fontconfig has got a bug? Maybe not. But waht's the matter, I wonder.
