Jerky playback Infuse 8.4.3

Video Playback

Good morning, I’m experiencing issues with versions 8.4 to 8.4.3 inclusive.
Playback of 4K 60fps MP4 photo slideshows from a Synology NAS on Apple TV is jerky and choppy, with the audio sometimes being out of sync. With version 5.9.6, using the same source, playback is perfect. I’m looking for some advice.

Which model Apple TV are you using?

Would you be able to upload a sample file we can review here?

Thanks for the help, I use a first-generation Apple TV 4K 32GB. I have the problem with photo slideshows with some videos between the photos. Normal movies aren’t an issue.
I upload the file.
