We received a few MacBook Pro's with the TouchBar running Sierra 10.12.1 (upgraded them to 10.12.2) and noticed when we have 2 users enabled with FileVault, the FileVault login screen is lagging and keyboard functionality is lost after clicking the users account icon. This behavior is happening to out-of-the-box machines with local accounts created (not how we normally deploy, but wanted to test this scenario). When I remove the second users account, there is no issue.
We have a support ticket opened with Apple, but curious if anyone else is seeing this issue?
