 '''Summary of the bug''': When displaying video from a capture device (in
 my case: Magewell USB HDMI Plus), the video will gradually fall behind.
 Right clicking on the window syncs it.  This is on macOS using
 AVFoundation.
 '''How to reproduce''': Use a command like the following to preview device
 capture output.
 {{{
 ffplay -f avfoundation -pix_fmt 0rgb -framerate 60 -i "1:none"
 }}}
