I have a problem with chrome performance. When i have two or more chrome windows, and one of them containing playing video (youtube) - then every other chrome window become jerky and not smooth at page scrolling or playing CSS animations (low FPS).

Here is screenshot of chrome task manager at the moment of scrolling: chrome with task manager

As you can see, GPU process is taking too much CPU resources.

I also noticed that dragging any window on top of chrome window (with playing youtube video) is not smooth too. Very annoying.

I tried to run chrome with --disable-gpu-vsync key and scrolling became smooth, but any CSS animation used 100% of one CPU core for max FPS.

With disabled vsync in nvidia-settings/ccsm has same effect, even with disabled composite.

So i dont know what to do. Firefox has not such problems, but i dont want to switch.

Output of chrome://gpu

My pc configuration:
i7 6700k
32Gb DDR4 RAM
Nvidia GTX1080 with latest nvidia driver-370
Ubuntu 16.04 / latest chrome/chromium (tried both)

update

This issue reproducing on other linux distributions with different DEs and composite managers. And not only for me.

So most probably problem in nvidia drivers for gtx10xx cards.

NVIDIA PLEASE DO SOMETHING

CHROME SUPPORT QUESTION + bug report

  • Did you try disabling hardware acceleration in Chrome? – edwinksl Sep 3 '16 at 21:02
  • @edwinksl, yes. Gpu process has gone, but vsync tearing started to annoying me :) – Vovan Sep 3 '16 at 21:12
  • I have the same. Did you solve the issue ? – wwvv Dec 27 '16 at 15:10
  • @wwvv, no. I tried other linux distros - but result is always same. – Vovan Dec 27 '16 at 15:48

nVidia is known for poor support on Linux I guess. Try using integrated graphics for chrome and the nvidia for other stuff. I cant even find appropiate drivers for my 760m where I can control which gpu to switch + basic power control.
