Text mode output is caption.text, which never holds ruby. It decided whether there was anything to show from region_count, so a caption with only ruby regions was output as text. Without CS, that event held an empty text and erased the previous caption, which only CS may do. With CS it failed: libaribcaption returns a NULL text when it is empty, and av_strdup(NULL) was reported as ENOMEM. Decide on the regions that are not ruby and hold a character instead. The text itself is not a reliable test, as it can hold line breaks without any character. Nothing to show gives no event, or the empty clear event with CS, as in the other modes; a NULL text is taken as empty. Add a text mode test on the ruby sample. The ruby only caption without CS at 5s now produces no event.
