For what it's worth, you can add YouTube to the list of Google sites with CPU consuming bugs - particularly in dark mode.

I'm not sure whether Chrome entirely fixes it, but if you watch YouTube in dark mode, there was a UI upgrade that they added that puts a "glow" behind the YouTube video player.

It's intended to look like a light strip behind your TV (but to me, I originally thought there was just something wrong with the monitor or my eyes), but in reality it's just more Canvas/GPU bound calculations running at 60fps constantly which would cause the CPU/GPU in the laptop to pull tens of watts, killing battery life.

There is no way to turn this "feature" off, other than disabling dark mode or blocking the "effects (do not remember exact item name)" DOM item in uBlock Origin. If you want to replicate this, go to a video on YouTube and use the three dots near the sign in button on the top right to enable the dark theme (may already be enabled). Play a video with bright picture, and after about ten seconds, you should start seeing "stuff" show up under the video as if it was a reflection.

There’s an option to turn these background fx off in the player settings
