Seems like you are working around a bug in the shelf. Why isn't the shelf
updating things correctly?

[Qiang(Joe) Xu, 2016/07/25 21:19:36]

Yes. The reason is shelf animation between transition users. This is one of the
solution, but not solving the root cause. I think showing new users' windows
should start after shelf transition animation finished. It needs more work to
do.

I don't like this solution actually. Let me work more on this.
