Interesting, I'm using chrome on windows. One thing I also dislike, if I may keep ranting to the internet, is how much windows has fucked with their windowing system in W10. For example: I'd be playing a game and something would cause the game to hang. It happens. But in windows 10 I couldn't even alt-tab because the focus would never leave the hanging 3d area. Couldn't control + alt + delete. Couldn't Windows key + tab, or alt + tab. Couldn't ctrl + shift + esc. Just had to hold the power button down. May I ask you: when was the last time you had to hold the power button down on your mac?

I'm using Chrome on windows too and it highlights normally on double/triple click. I think you either have malware on your computer or you have an extension that is... taking some extra liberties with your browser.

As with all initial debugging steps, try in incognito and see if you have the same behavior.
