The problem seems to be (just guessing here) that text rendering is slowing

I'm actually kind of distressed about this because of the prospect of spending

Is there a work-around? I've tried a few different fonts but that doesn't seem
to help.

Hi Jerry,
I reported the very same sysmptoms a few weeks ago but until now it
seems I was the only person to see it, although I could see it on 2
machines (different OS versions of windows, different CPU different
graphic cards). So I am somehow glad it's happening to you (sorry).
I did not have that problem with LyX 2.0.1, so I would advise to try
that version instead and report if it fixes the issue for you too.
Best regards,
Olivier
