Try watching Netflix in Firefox or Chromium. Or enable smooth scrolling in Firefox and hit PageDown a couple times. The issue with scrolling can be resolved by enabling hardware acceleration, but this isn't the default in Firefox and the obscure config breaks from time to time. Until hardware acceleration becomes the default, not an opt-in, I consider this feature broken. Aside from Netflix, I'll sometimes see tearing even on YouTube, when I put it on fullscreen. Luckily, there is mpv with builtin youtube-dl support, which solves this problem. But I haven't found a solution for Netflix, other than rebooting into Windows, or switching to my Mac.
