I did https://bugreports.qt.io/browse/QTBUG-60429

(as I mentioned in bug description I thought that it was due to that
currently in qt 3d calling both QBuffer setData/functor and partial data
update can lead to unexpected behavior. Did the patch to improve that:
https://codereview.qt-project.org/#/c/192767/ but it hasn't solved this

With regards, Oleg.
