[IMX6] Rendering issue with TimelineEventsApp on Boundary

Using a sample app that is not currently part of the isEmbedded Ensemble8:

javafx -cp dist/En* ensemble.samples.animation.timelineevents.TimelineEventsApp

On my boundry devices, I am seeing the button highlight shadow rendered in the wrong place, often crossing the middle of the button.

I don't see any reason in the sample that the code should not run on embedded.
