I think it is:
1. Yes, used https://www.dailymotion.com/us with some random muted video playing. (on the tests before, used facebook)
2. Yes, the screen sleep is set to 1 min.
3. New profiles used, HW acceleration on by default in Nightly.
4. It's quite possible to be hardware related, even narrower:  might be specific to a certain combination of HW / OS / drivers

colormatch, tallyo, could you please help further by listing the hardware (processor/video card and if it's a desktop/laptop) and exact version of OS both of you can reproduce this problem on. I'll try to find and use something closely matching your HW? Also, something is intriguing me from comment 10 :

so, could not hurt to double check if it is equally easy for you to reproduce the issue on a new clean profile.

I've attempted to reproduce the issue with a nvdia GPU on win 10 machine, and the profile seems to yeld nothing special http://www.perfht.ml/38SIM0g (cannot upload the profile with the screenshots to prove animation, since it's too big for upload - might've been already blacklisted from perfht.ml for trying).
