From: Thomas Hellstrom <thellst...@vmware.com> If the application hasn't done any drawing since the last call, we would reuse the same back buffer which was used for the previous swap, which may not have completed yet. This could result in various issues such as tearing or application hangs.
In the normal case, the behaviour is unchanged.
