Bug in Project 2013 when turning off screenupdating in vb

Question

Below a short (3-line) piece of code that turns off screen updating, applies the "Gantt Chart" view (though any view or table produces the same effect), then turns screen updating on again.
When you run the code, the result is all task names and gantt chart bars disappear - only the dependencies remain in the Gantt chart. making ScreenUpdating = True restores them again.
Has anyone else seen this potentially major bug? It seems like turning screen updating on again after turning it off doesn't refresh the screen.
Sub screen_updating_problem()
    ' Make the next line "True" to fix the problem, i.e. not update the screen
    ScreenUpdating = False
    ViewApply "Gantt Chart"
    ScreenUpdating = True
End Sub

Regardless of the need to turn screen updating off and on, clearly it's not working and it's a bug. This is my point.
If I turn screen updating off, change the view, then turn it on again, regardless of whether this is needed or not, turning it back on removes the Gantt bars and text in the tables. This should not happen.
Let me give you an example:
1. Open all tasks (removing the filter and opening all summaries)
2. Close the lower pane
3. Go through a set of operations to determine the 1st, 2nd, 3rd, etc. critical paths from a selected milestone
4. Add a column to the table
5. Filter on the critical path to the selected milestone
If I do this when screen updating is on (especially in step 3), the user can see each step of the process. We don't want this. We want to turn screen updating off so the next thing the users sees is the result, and non of the intermediate operations that
involves changes to the screen. Turning screen updating off while it goes through each step makes each step also makes it run faster, because the screen doesn't have to be updated.
What we are doing is relatively complex. Again, right or wrong, turning screen updating on after being off doesn't behave correctly.
