Ouch. It could be something like some configuration being present
(or not) in $HOME for the hinting and/or subpixel rendering settings
for fonts, for example.

Yes, or even have a separate home directory for each test case
being run. Or point $HOME to an empty, non-writable directory (not
sure if that would work). We may want to also set $XDG_CONFIG_HOME,
$XDG_CACHE_DIR, and so on.
