Abyss of Pandemonium post-boss texts not displaying in full

Looks like this:

Not sure what could be causing it. Running on vkQuake. Ditto for the Forgotten One.

Both Mission Packs display their texts without stopping dead center like this, so I don't think it's vkQuake, and I've seen a youtube video of the Legond post-fight text without error so I know this isn't intentional.
