There was a short freeze when using (the terminal emulator) Terminator. When
starting it from command line it crashes at some point with the following
message:
python2: cairo-scaled-font.c:459: _cairo_scaled_glyph_page_destroy: Assertion
`!scaled_font->cache_frozen' failed.
[1]    26494 abort (core dumped)  terminator

I am on Arch Linux, but it's not completely vanilla, so I'll give you what I
think might or might not be important details:

- Kernel with ck-patchset

- Fontconfig infinality (
<a href="https://wiki.archlinux.org/index.php/Infinality-bundle">https://wiki.archlinux.org/index.php/Infinality-bundle</a> )

- Compositor compton

dmesg doesn't really tell much:

[ 4000.214394] [drm] stuck on render ring
[ 4000.214395] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[ 4000.214396] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[ 4000.214396] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[ 4000.214396] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ 4000.214396] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.

Before and after nothing related to the freeze.</pre>
