Xbox One Pixelization - Local Playback - 20+ Mbps

Hi All,

When playing High Bit Rate files (Playing files in original output mode 20+ Mbps) the xbox one will start to show vertical pixelation banding and will drop frames. If the user pushes the output file playback to a locked 20Mbps everything is fine. Now this happen both on xbox one preview software and non-preview os versions of xbox one. Has anyone else come across this issue? I know this wasn’t an issue before, what’s changed?
