Screen tearing and frame buffer issues on dual monitor setup

hi,

I am using dual monitor configuration on Ubuntu 19.10 with Unity desktop. Everything is working correctly in this configuration:

but when I change it to this configuration:

Attachment 32419

I am having huge screen tearing and the desktop shows randomly large chunks of multiple frames (several frames mixed in the frame buffer). The screen is stable, though, no flickering, etc. The issues appear on both monitors.

I already applied this solution: https://github.com/bauca/graphics-switcher

My hardware is i7-8700k iGPU and 2x 1080p60 monitor.

Do you think a dedicated graphics card can solve this problem?
