On Windows 10, I cannot two-finger-scroll in Google Inbox with Chrome
Solution 1:
Try entering chrome://flags in your adress bar, searching for Enable touch events and setting that dropdown to Disabled. Recent versions of chrome do strange things on some pages that rely on detecting touch capabilities. Honestly I don't know why, but disabling touch events usually fixes the issue. You'll be left without touch support though, which may or may not be a dealbreaker for you.
