I unplugged my nvidia GPU due to the constant screen tearing (even with drivers installed) thinking that I wouldn’t have that problem using the Intel Integrated Graphics, unfortunately the screen tearing persists . I’m using an Intel Core i7 6700k just in case.
Tearing can be due to many causes - screen size, hardware support for video decode etc. Can you explain exactly what programs are showing tearing, what screen resolution you’re using and maybe other relevant info?
My monitor is a S22F350 (22 inch) running at a 1980x1080 resolution, 60Hz refresh rate, connected via HDMI. Tearing occurs whenever I’m watching videos or even scrolling in web pages.
I decided to try another browser (Chrome) and the tearing was gone, even when setting up the nvidia GPU and the drivers. Thanks for all the help and shame on Firefox.
One thing to keep in mind for good video is hardware acceleration which is through either VDPAU or VA. I haven’t had a chance to look into this on ClearLinux much but try this

If the Hardware Video Acceleration library (libva) is installed then programs like VLC, mplayer, etc., will probably use it. Firefox does not. Chrome and Chromium do. For nVidia you’ll need VDPAU instead (export VDPAU_DRIVER=nvidia) and libva can then piggyback off of it.
If you’re using the Intel i965 driver for X then ClearLinux sets up libva for you. I doubt for nVidia and I suspect no way for an Optimus based laptop.
This isn’t caused by Firefox. They can’t really solve this problem. Only if content providers(youtube/netflix etc.) stop using proprietary media formats will the problem go away.
