I had the same problem with firefox and I solved it by changing layers.acceleration.force-enabled to true. here is how:

type about:config in the address bar, hit enter, click on Accept the Risk and Continue, find layers.acceleration.force-enabled and change it's value to true then restart firefox.

You can test if you're still having the tearing problem by watching this video on 1080p and 60fps:

For chrome, it is enabling hardware acceleration in settings and enabling flag chrome://flags/#enable-accelerated-video-decode

GPU acceleration status is listed here: chrome://gpu/

For me, after turning the flag enabled, the video decoding became hardware accelerated(previously was software only)
