Actually has nothing with playing multiple songs in a row. Happens when trying to load OnlyMyRailgun on my computer -- not sure why the binpacking would do the wrong thing on my system.

Slightly different font rendering? The real problem here, of course, is that there is no support for expanding the atlas if it gets full. Also, I assume this is in romaji+kanji mode, which causes the maximum pressure on the atlas, no? If it happens on other modes too I'd be inclined to think it's some weird degenerate condition.

Can you get a dump of the atlas at the point where it errors out?

Couldn't reproduce recently, closing. Not sure what caused it to fail at that point.
