Thanks for your reply.

This just happened again, and I checked the memory.

RB's mem usage had gone up to 102 real, and 460 virtual

There was still several hundred MB of free memory.

This seems high. I had been suspicious of a mem leak in RB once before. Also to trim down memory use I removed all the built in behaviors from the app package (I don't use them) - maybe I'm only saving a little.

One of the other video artifacts of this issue is that RB's own fade in / fade out animations are slow and jerky. Like I said, quit and relaunch RB and all is well again. Now that I've purchased RB, I might just run a nightly cron job to quit and relaunch it.
