 seems 8.5a9 is the first broken release for you and the patch for #28329
 the likely culprit.

 Confirmed. This is the result of using an
 [https://developer.android.com/reference/android/view/View.html#setClipToOutline(boolean)
 object method] added in a more recent API-level than KitKat (18). I'll
 correct this in the next branch I push for review on #28329. I'll also
 confirm there aren't other similar errors that will trigger after we
 correct this one.
