Ubuntu 20.04 Second Monitor Lag NVIDIA Driver 535.183.01

Hello Nvidia People,

I’m having a problem that has already made me lose my patience!
The problem is: My second monitor starts lagging after some time of use, specially after a suspend or running demanded tasks like using CUDA for Machine Learning.

This is my setup:

To troubleshoot this problem, i already tested other drivers but no one solved the problem.
After that, i already re-installed ubuntu and then made “sudo ubuntu-drivers autoinstall”, which made the graphics driver update from “Using X Org X Server - Nouveay display driver” to the “Nvidia driver metapackage from nvidia-driver-535(proprietaty, tested)”, but this unfortunatelly didn’t solve the problem.

I would appreciate if there’s somebody that can help me to solve the problem!

My bug report obtained after the second monitor start permanently lagging.
