Screen Tearing NVIDIA Optimus

Hello, I'm currently using Garuda with the MATE desktop and have no issues except for one - Screen Tearing. I have an external display with 75hz that I use as the primary monitor, but screen tearing occurs on the internal display, too.

Any tips?
Laptop specs:
i5-6200u
GeForce 920MX
8GB 2133mhz ram

Press Pencil and look what I changed, its all in the wiki link I post.

Check Mate Troubleshooting. It suggests to disable compositing with nvidia. If this solves tearing, maybe use picom for compositing.

Yes, that solves the issue, but I don't really know how to setup picom
Could you please tell me how?

Normally, you would include a picom command in your autostart applications/scripts (the Mate way?).
I suggest you test default settings at first. Then depending on your specific needs (values, multihead etc.), find which configuration fits best and create a conf file in your home dir, following Archwiki advice and reading the manual.
