Comment 25 for bug 1825626

A discussion at https://forum.manjaro.org/t/desktop-gnome-frequently-get-frozen-few-seconds-and-works-again/81603/29 for manjaro seems to nail down:

* It looks related to mutter (a gnome desktop component), since some guys report that the freeze disappears when updating mutter.
* It does not seem to appear under under non-gnome desktop.
