Description jason 2015-11-11 18:43:10 UTC 
If a string cannot be wrapped within the wrap limits due to having no space, then the text starts overwriting itself.

It should at least arbitrarily split a long line, even if this isn't language correct, as overwriting the same line is no help at all.

patch

small workaround: an unbreakable line doesn't render overlapped 

and also clear kerning at beginning of line.

"and also clear kerning at beginning of line."

This one is actually an issue. it can remain a prev_index and do a kerning with "space" and "A" for instance, and you get a negative xstart. which a cause of overlap.
