Video stuttering



Hi, I have issue with video stuttering when watching 4K HDR stream. Issue started to appear by updating to v21. I tried many settings as well as adjusting Cache in Services. When I open video with external player there is no stuttering at all.

I also tried to install v20.5 and there is also no stuttering. Any idea? Which difference between v20.5 and v21 can cause this?

Device: Nokia 8010 4GB RAM
Internet speed is 190 Mbit/s

Thank you
