Hi Gurpreet,
Can you check if this bug is gone with the latest Nightly?

Hi Blake, Still choppy and lot of frame drops. Would sometimes freeze for 1-2 seconds. Same video in both Chrome and Edge works fine. Tried with both graphic cards also, Intel 530 and Nvidia 960m. Also tried in safe mode. Same result. Also works great in Firefox Beta.

Thanks

Also this problem is only on 4k 60fps.
