High CPU Usage on Chrome 49
Recently, I've noticed that Google Chrome (not chromium) has been using a ton of CPU, sometimes upwards of 90% across multiple cores, but only on specific sites. The most prominent being facebook, where the UI seems to flicker whenever I try to use it with hardware acceleration on (when hardware acceleration is off it still uses a lot of CPU, but it doesn't flicker). When I tab away from the page, the usage drops down to normal.
I'm currently using a 2015 Thinkpad X1 carbon, so I don't think I should be seeing facebook using 100% of my CPU, so I'm wondering if I have something mis-configured or not installed that should be.
Anyone know if there's a way to fix this?

I'm using the default Intel graphics driver. It's labeled as the i915 driver when I ran lspci -v

Re: High CPU Usage on Chrome 49
Can you confirm the issue with some other browser, perhaps Firefox.
Also, give this a try: https://wiki.archlinux.org/index.php/In … nd_Firefox

Re: High CPU Usage on Chrome 49
I tested the default gnome web browser and firefox, and both seemed to use around 40% CPU when scrolling on facebook but neither caused the ui to flash like chrome (firefox was the smoothest of the three). I tried setting AccelMethod to "uxa," but everything else on my computer seemed to grind to a halt and started lagging horribly. Chrome did use much less CPU though, I didn't see it go over 30%.

Re: High CPU Usage on Chrome 49
So you're saying Chromium works, but Chrome doesn't? So... that's pretty much expected. Chrome ships its own libraries and other stuff which can cause issues. If you want pepper flash or widevine, install that from AUR.

Actually no. Up until now, I didn't have Chromium installed.
I just installed it to test out whether it was an issue with Google's Chrome, and it seems like installing Chromium fixed my problems with Chrome. I'm now back to idling around 2% CPU on facebook, and the flickering is gone.
