I’m running latest Plex Media Server on an Intel 11400 under Linux 5.11 kernel. When I turn on hardware encoding (just hw decoding is fine), I get green artifacts. This is especially evident when transcoding Live TV & DVR streams. Is there a fix for this? And is anyone else running into this?
Bump. Anyone can help?
Have you tried following this?
According to @scuffe in that thread, it seems like 5.11 kernel is what did the trick. But I’m already on the 5.11 kernel…
Are you running plex in a container or just installed on your os? The 5.11 kernel and the latest intel neo packages was the trick for me. Green artifacts and a generally distorted screen always happened if i enabled HDR tone mapping while hardware offload was enabled. If i disabled either of those settings it was fine but it would either eat up the CPU if hardware offload wasn’t enabled or HDR content looked bad because there was no tone mapping. If your running in a container i linked the dockerhub repo that i pushed the image to. The dockerfile that i used to build it is also in the thread if you would rather build it yourself.
I’m trying to find a solution since long without luck.
I have a baremetal server with a i5 11600k running Ubuntu Server LTS 20.04.2 with OEM Kernel (5.10) and the green artifacts are always there (with our without HDR).
I’ve installed the latest drivers from here:
But the fact is… there is no solution. I’ve tried everything without luck…
The only way I’ve found to avoid the green artifacts is to Transcode to a lower resolution than the source. The green artifacts are happening to me if the source is 720p and the server transcode it to 1080p (just for giving an example).
That’s the only information I can add to this issue. Hope they can find a solution soon…
I’m running plex in docker on a 11700k, Ubuntu 21.04 with the 5.11 kernel. Yesterday I got a complaint about the green artifacts. I could only seem to recreate it when the source was encoded with VC1. I was able to transcode 4k HEVC without artifacts. Toggling HDR seemed to make no difference. I followed the instructions here (How to upgrade Ubuntu to 21.04 and kernel to 5.13 – ignore the upgrading ubuntu section and go to the bottom) and upgraded my kernel to 5.13 stable and it seems to have corrected the issue. For now.

Nice. That’s good to hear. Waiting for 5.13+ to be available for my distribution (Proxmox)…
