Server Version#:1.30.0  
Player Version#: 1.30.1 latest

Hello,  
Here is the symptom: the player cannot read 4K videos. It’s more than choppy. Probably a frame every 15 sec or so.

Here is my configuration:

**Plex Server**

- Runs as a docker container using linuxserver/plex:1.30.0.

- I have added this to my docker-compose.yml:

```auto
 devices:
      - /dev/dri:/dev/dri

```

- It runs on a linux VM on vmware. 2 cores, 8GB ram

- Intel Xeon based, no GPU

**Plex HTPC**

- CPU N3350 / 4GB RAM

- Runs on lubuntu 22.04.1 LTS

- Plex-HTPC Version 1.30.1 latest, Uses WebGL

**Facts:**  
The player can play 4K videos from the network (using VLC)  
I can play 4K video from plex-web (plexserver:32400) in a browser from a windows VM (no GPU + RDP)

How can I fix this ?  
Is there a way the video is read like it simply could through NFS (which works with VLC) ?

Any help much appreciated.  
Thank you

Are you using EGL ([Testing Linux EGL](https://forums.plex.tv/t/testing-linux-egl/776726))? Note: it fatally breaks the app with some drivers which is why we don’t have it enabled by default.

Thank you very much.
