Hi and thanks for filing a bug report (FB20741484). Looking at your bug report you mention a sample but you don't provide a link to it. Please add a link to the sample you're talking about to your bug report. Also, for best results it would be very useful if you added your own sample and some specific directions that can be used to reproduce the problem.
