Comment (by Peter Bennett):

 Other issues:

 I have noticed another artifact on the shield with playback of 23.98p fps
 material at 1.2x on a 4k60hz p display. every second or so you see an old
 frame where the motion jitters. I suspect this is frame stretching but the
 page buffer is still flipped

 Ive seen another avsync2 artefact (on shield). I was watching a program
 (1080i 25fps) at 1.2x on 60Hz TV. Smooth playback for 5 secs then about 2
 secs of drop every 2nd frame. Note 25*2*1.2 == 60Hz so there must be some
 synchrony issue.
