One thing you can do is to reverse-bisect between wine-staging and upstream
wine. Of course, that's not ideal in its own ways. It's a rather unfortunate
case when a game depends on several wine-staging patch sets.

Another possible approach, that may be helpful enough here, is to try
individual wine-staging rebase versions between 5.9 and 5.10 That doesn't
constitute a full bisect, of course, but would at least narrow down to the
commits for a particular day, which may be enough of a clue in itself to make a
good guess.
