Notes:

• Using UITextView is a great alternative to multiple line UILabel, without the bug. UITextView does not exhibit any of the IULabel other oddities either, like alignment errors or flickering.
• There is also an alternative solution on SO-25947146, which did not work for me but is worth mentioning.
• Seems to occur prominently when self.tableView.editing is true
• Using low values for tableView.estimatedRowHeight reduces the occurrence
