Example URL:
maps.google.com

Steps to reproduce the problem:
Visit any one of various sites including:
- Google Maps (any location)
- Google Drive Sheets (any new blank sheet will do)
- https://cryptowat.ch/bitfinex/btcusd

What is the expected behavior?
Responsive site with nominal CPU usage.

What went wrong?
CPU usage is pegged at 100% while tab is active and site responds very sluggishly, if at all.

Does it occur on multiple sites: Yes

Is it a problem with a plugin? No 

Did this work before? Yes 59

Does this work in other browsers? Yes

GpuProcessHostUIShim: The GPU process exited normally. Everything is okay.

I have one other easily accessible computer to test this on with different hardware and it does NOT reproduce on that computer, performance is acceptable with hardware acceleration either on or off.
