Looping Playback in dashboard isn't smooth/clean- hiccup at loop point
Anyone else seeing a hiccup of varying intensity when playing back a simple loop in Dashboard Mode? I also see it when playing in the timeline as a new segment and as a two videos sequenced together. I've been seeing this for awhile now in Millumin 2, but not in Millumin 1 and finally got around to testing it thoroughly. I have a simple video of a white bar rotating on black - 10 seconds long 1920x1080 - HAP and the hiccup on the loop is always present but sometimes more pronounced. Checked the loop is good in After Effects, Quicktime, and Scratch Play. This is running on a 2016 MacBook Pro Quad Core i7 with Sierra 10.12.6 specs below:
Processor Speed: 2.7 GHz
Number of Processors: 1
Total Number of Cores: 4
Memory: 16 GB
Radeon Pro 460 4096 MB
Files are on the local SSD flash drive which also has plenty of space. Restart/Shutdown with nothing else running does not change the behavior. This machine shouldn't be particularly taxed by a single layer of HD video and shouldn’t be experiencing a performance issue, so possibly there’s a bug related to looping playback?
