My own tests seemed to indicate otherwise. Mine ran on multiple monitors as
well (typically 2-4) in XP, Vista, and 7 and across cards from the same
manufacturers (it's been too long for me to remember the exact models). Did you
notice tearing on all machines with multiple monitors using the old code? Or
did you notice tearing on one, make your changes, and then test on the others
afterward?

My concern is that this is a step backward as the decision to use multiple swap
chains instead of multiple devices was a conscious, weighed decision and a lot
of effort was put into making it work right.

I don't know of anyone else who has reported this issue and I know there's more
using it than you and I and so your setup/configuration seems more suspect IMO.

If multiple devices is truly necessary, I still feel this patch needs to be
revisited and revised and address some of the things I've noted. We shouldn't
be committing things known to cause memory leaks/issues.
