Apologies to all; I don't mean to treat this list as my own personal development blog. However, here's a rock steady 50Hz, full-screen rendition:

Takeaways: • the border masking is overdraw and I'd rather fix the problem by just not drawing incorrectly in the first place; • that being the case, I've only properly profiled the unmasked version, and found it takes no more than 60% of the available CPU time per frame in its current state.
