Rachel,
Please use the test case at the top of the bug.
There are also other bugs which may make mutter appear to not render at full speed. Most notably:
https://gitlab.gnome.org/GNOME/mutter/issues/406
but also most of:
https://trello.com/c/Q6JYXPPs
You need to be careful to not confuse this bug for those others.
