Show episodes jumping around near end of episode

[tyler.of.athenry]

In the last week or so I've noticed Jellyfin jumping around near the ends of lengthy episodes (~45minutes).

I thought clearing transcode cache fixed this after suspecting heavy CPU load led to the issue. However, today I cleared transcode cache and continue to see the same issue in the same spot in the episode.

Could someone guide me towards some steps to take to troubleshoot this?

A few variables perhaps worth considering:

1. Roku app has been updated to the recent new releases
   
2. I've transcoded much of my library to: MP4, HEVC, AAC
   

I am on 10.10.6 and use with Nvidia hardware enabled
