Youtube Screen Tearing Solution?

[wrender]

I have been wondering what is the recommended way to stop tearing in playing videos on youtube in firefox with the latest kde neon and nvidia drivers?

I have come across various things related to the nvidia driver, putting in triple buffer setting, force full composting pipeline, or in the kde compositor force full screen repaint and opengl 3.1. What is the correct way to deal with this?

Not to be flippant, but the 'best way' is the one that works for your particular use case. The first thing I would be playing with is changing the compositor being used. One is likely to resolve the issue.

I tried various combinations and got rid of the screen tearing however now I get less smooth playback... Not sure what settings are bad or good. My system can run Doom 2016 in Ultra mode full HD, so Youtube should run like butter.

Is this *just* firefox? Or is there tearing in general? Stock Nvidia driver or proprietary?

You may have to look at Enabling OpenGL Off-Main-Thread Compositing (OMTC)



This Polish mozilla forum thread has some other FF tweak combinations to try if the first does not work

This is with Nvidia proprietary drivers. I only noticed it Firefox so far as that how I stream all my content. ie YouTube, Netflix... etc.
