Hm. Well, now that 8.4.2 is out, the first thing you ought to do is
update and see if this happens to be resolved by any of the recent
fixes. (I'm not too optimistic about that, because it doesn't look
exactly like any of the known symptoms, but an update is certainly
worth your time in any case.)
If you still see it after that, please try to extract a reproducible
test case.
