PostPosted: Tue Mar 27, 2018 8:46 pm    Post subject: Chrome constantly freezes the whole system Reply with quote

After an update on 18th of March, my chrome started slowing down the whole system.
It becomes very obvious when I navigate to a website that has a lot of animations for example, like giphy.com. I tested Firefox and it performs as expected.
When these freezes happen - chrome's CPU usage is through the roof, and when moving the mouse fast, the cursor freezes for ~0.5 seconds and then jumps 200-300px at a time.
Looks like at least one other person has (or had) the same problem and confirmed that in this thread: https://forums.gentoo.org/viewtopic-t-1077690-highlight-chrome.html
Has anyone else seen anything like that or has any ideas?
Many thanks!

That's a good question! The OpenGL itself is definitely operational - I can play CS:GO and other games. How do I check if it works for chrome/system? WebGL seems to also work as expected when I try http://arodic.github.io/p/jellyfish/ with 9999 jellyfish (it gives me ~25fps, and no visible lag to the system/cursor/anything)

If it's broken you'll see a lot of red text in chrome://gpu (along with other symptoms like laggy scrolling), but it sounds like that's not the root cause. Posting a glxinfo -B wouldn't hurt.

Is there a way to check if it is video-card/opengl related issue? Because I am not completely sold on that it is, after all, webgl works perfectly fine.

Try to disable 'Use hardware acceleration when available' option in settings

That worked, it will definitely do as a temporary workaround - thank you!! Any idea on what may be causing hardware acceleration to lag the system?

Probably cause by nvidia-drivers

First step is checking if a older version of nvidia-driver cause problem.

I finded this on nvidia forum https://devtalk.nvidia.com/default/topic/1029164/linux/chrome-tearing/

Thank you so much for the link provided. I will test downgrading chrome and/or nvidia-drivers on the weekend or next week and will post back the results.
