Not sure if this is an issue with the docker specifically or emby itself, but ever since 4.7.x screen grabber has not been working for me for thumbnail generation.
Log of the error: https://pastebin.com/8wBhzTzQ
I have tried going back to older version and all 4.6.X versions on the github work just fine, none of the 4.7.x versions work for me, no other settings changed.
Would be grateful for any insight
Unraid version 4.10.3
