#39560 closed defect (bug) (fixed)

4.7 About page causes high CPU usage

Description (last modified by SergeyBiryukov)

Upon the upgrade to 4.7, some users reported a 100% CPU load after being redirected to the About page, apparently caused by three videos set to autoplay simultaneously. Others made a point that it's also a bad UX for users with slow and/or limited mobile data plans.

We should try to fix it in 4.7.2 or at least avoid doing that for future releases.

Patch looks good to me. @SergeyBiryukov or @voldemortensen are either of you good to own this and land it in 4.7.3?

I think the patch looks great, although I'm not sure we need to remove the loop attribute. That's not really the problem. Having said that, I don't care either way if loop is removed. +1 on commit.

I'd totally second this and recommend to always avoid video playing automatically, for accessibility reasons too.
