pw_char and batching?

I've noticed a problem batching around a bunch of pw_char's to a retained
canvas. Essentially the window doesn't seem to be properly refreshed
after the pw_batch_off, with lots of characters missing. If I pull up the
window frame menu and select Redisplay, the missing characters appear.
This is on a 3/50 running 3.5. I don't do anything funky with batching,
just a simple pw_batch_on, followed by a bunch of pw_chars (in odd
locations, which means I can't use pw_text conveniently) and then a
pw_batch_off. I've managed to work around the problem by using pw_rop
(with the proper arguments) instead of pw_char and batching works
properly, so I believe the problem lies in pw_char. Has anyone else
noticed anything similar?
