Good afternoon dear forum,

A wild guess, but search for "nvidia" and "disable opengl flipping" on this forum.

Thank's, this works well only if I set nvidia mode. So if I'm on Hybrid mode or Intel mode flickering persist, so I thinks this is intel problem and not nvidia problem.

True, the intel driver offers a similar option. It is just slightly more complicated as it may require creating your own xorg.conf. And some research on what driver your intel GPU is using and how the option for OpenGL flipping is called.

Well, I use xf86-video-intel. There is not an option called OpenGL flipping or something. I'm looking inside arch wiki but there is not. :(

Fixed with Nvidia-settings->X- Screen0 -> OpenGL Settings -> Allow Flipping disabled
