Setting :use-markup and :text is currently not idempotent, and it depends on the ordering, e.g.: g_object_set (actor, "use-markup", TRUE, "text", value, NULL); does not yield the same results as: g_object_set (actor, "text", value, "use-markup", TRUE, NULL); This is particularly jarring when using ClutterText from ClutterScript, but in general GObject properties should not rely on the order when used from g_object_set(). The fix is to store the contents of the ClutterText as a separate string from the displayed text, and use the contents, instead of the displayed text, when toggling the :use-markup property. Let's also add a unit test for good measure, to try and catch regressions. https://bugzilla.gnome.org/show_bug.cgi?id=651940
