Server Version#: 4.157.0 Ubuntu

[Plex cpu usage.zip](https://forums.plex.tv/uploads/short-url/oRzylQZOlA9IE1O6srPYiFt52pb.zip) (1.8 MB)

Player Version#: 1.112.0.359-0d79s49f

Recently I have noticed that when the server is working (detecting intros, chapter thumbnails etc) Plex player for windows starts using high (60-80%) cpu even when not playing a video, just having the app open (see video). Has anyone else found this? Is this an option on something I just need to switch off?

Thanks

Could you check if the [hosted web app](https://app.plex.tv/) is exhibiting the same issue?

Hi, No it doesn’t and neither does the linux version of the Plex Player, This is the web player while watching a video and the other is the linux plex player. The windows plex player is installed on 2 different versions of surface pros and does the same thing on both.
