Edward thanks for posting and your right with gpu acceleration off fixes the bug, great find. It would be frustrating enough if this glitch just affected the previews but it also affects the export even when exporting with the “use previews” option unselected. The only way to make the transition work correctly is to export with gpu acceleration off.
Ryan thanks for commenting on this post with your test results also and don’t worry my feelings weren’t hurt by the discussion I knew I was right I just hadn’t convinced the other posters that it was a bug or perhaps they didn’t have gpu acceleration turned on and so wasn’t seeing what we saw?
