I've been having an issue for quite a while now and it doesn't seem to have been fixed with macOS Sierra. So I decided to bring it to MacRumors. So, in Safari after a certain amount of time, elements on a website some kind of freeze. For example, just a few minutes ago when I was at Facebook elements wouldn't 'animate' (when hovering over like button to get those extra options e.g.). This happens quite a lot. Not on every website opened at once, but mostly just one or sometimes two. I can however click by the way, it's really that the animation is gone. The thing is that restarting Safari sort of fixes the issue. But then again, after a certain amount of time it happens again. I have no idea what causes this and would like to know if others are having the same issue, as well as whether there's a more permanent solution?
