Roku OS 15 Possible 4k playback Issues Data Collection Request

I am having the 4K playback issue trying to play 1080p videos. The issues I am experiencing are:

  • solid green screen or green tinted screen
  • Frozen frames
  • Sped up or slow playback
  • Audio stops playing or unsyncs
  • Blocky/Pixelated images
  • Outlines for last frame stuck in video

Model: 4850X - Ultra

Software version: 15.0

Source video:

  • Resolution: 1080p

  • Codec: HEVC (H.265), 10-bit

It looks like from the logs, that Plex is transcoding 1080p content to 4K (3840x2160), even though the source video is 1080p. Even when Roku’s system resolution is set to 1080p, Plex still initiates a 4K transcode.

My Plex Server is on a AMD 12 core 5900X and CPU usage is minimal while the issues happen.
