Macbook Pro 16-inch 2019, frame drops while playing youtube video in Edge

From past few days I have been noticing frame drops while playing youtube videos in Edge. I think it is after I updated to Big Sur 11.5.1 (20G80).

I interesting thing is that, frame drop always happens when touchbar goes off (after sometime automatically ) and also when it wakes up (if I use touchpad or keyboard)

It was not happening before and I think it is due to the update, any idea how I can fix it ?
