Ghosting MKV files

[gosna]

Hello, let me preface with devices.
Server:
Ryzen5 5600x
RTX3060TI
32GB RAM
Windows 11 fully updated
Jellyfin ver. 10.8.13
Jellyfin Media Player updated (for testing)
Alienware AW3235QF 32" curved OLED monitor.

PC streaming content:
I5 6600k
GTX 1060
32GB RAM
Windows 10, most recent update
Jellyfin Media Player fully updated
Old Samsung Plasma 1080I TV

Issue is on MKV wrapped media, im having very bad red ghosting during any movement when the streaming pc is decoding the content itself. If i force the server to transcode the file (did this in the media player by "allow transcode" checkboxes 1 at a time untill it showed a clean picture, which was "allow transcode AV1"), it works perfectly fine but nearly cripples my 5600x, for a single stream of the animated tv series Archer, it consumes 2 processes at 40% cpu usage each for the single episode that is being streamed. the processes are FFMPEG if i remember correctly.
This is seems like a transcoding issue on the streaming PC side, but im not well versed enough in this type of media to understand if i need to find codecs to properly handle these files, or or if the I5 simply doesnt have the correct insructions to properly decode whatever is under the wrapping of these MKV files.
I assume i will be asked what these are under the wrapper (i assume AV1, due to the fact allowing transcode for AV1 fixed the issue visually but created another problem), what is a good program to use to get under the hood on these files to get to the bottom of this?
this issue does not occur on the server itself, watching the videos they are fine on there.

So the video's codec is AV1? And which client are you using? Jellyfin Media Player?

Correct, i did verify through the handy tools already in the application that these are all AV1 that i am having an issue with.
I also need to correct myself on the device that is streaming from the server, it has a 1660 super.

And yes, the device streaming from the server is using the jellyfin media player.

Since you're using Jellyfin Media Player, try changing the hardware decoding options found in its client settings.

It has three options. The first two use the GPU. The last option (decode.disabled) will playback the video with the CPU instead.

This is a known issue with JMP.

You can try @Efficient_Good_5784's suggestion, but I think it has more to do with the AV1 decode library that JMP uses, regardless if the work is done on the CPU or GPU.

There seems to be a problem with changing that option, when i disable it, i would expect the CPU to spike, but it continues to use the GPU, same average as before, about 37% usage, no matter which option i use, enabled, copy or disabled, and i restarted the program between changes just in case.

This is strange, as i can watch the same media on the other rig, using JMP and the 3060ti/5600x does not encounter the same issue.

In the git ticket I linked, it was noted that the problem is inconsistent and the severity varies user to user.  The OP shared a couple test videos that severely triggered the problem for them, but barely triggered it for me (I'm solidsnake1298 in the ticket).  I've yet to experience this problem in JMP with my own media.  I'm using an AMD graphics card, so maybe it is an Nvidia + JMP thing?  IDK.

TLDR; its a known issue.  But when version 10.9 is released, AV1 should direct play in most browsers.  So there's that workaround.
