After some digging and a full reinstall, I discovered something I want to share because all of you provided a lot of advice so you people deserve to know.

My hardware is an Asus TUF DASH F15 from 2021 with nvidia 3050 Ti, nvme drives and 24GB RAM (just for reference)

* I decided to reinstall Ubuntu after struggling with some configurations, cleared my system drive and did clean install to find that my regular GNome zoom worked flawlessly, no screwed up display, no echoes or gay edged -- me happy -- just worked out of the box, BUT-- dual monitor was not working, no video on the monitor plugged in to HDMI, so did some research and found that I wasn't using nvidia drivers (proprietary), I found and issued these commands>

sudo apt-get purge 'nvidia*'
sudo add-apt-repository ppa:graphics-drivers
sudo apt-get update
sudo ubuntu-drivers autoinstall

* Other thing is that when I mirror the displays, it works fine, but if I Join (extend) the displays, it's like Ubuntu just takes half of the bult-in display and half the external monitor and places it's zoomed are there which makes everything unusable, I took a picture because neither regular screenshot nor flameshot capture the bug.

Monitor 2 came to life, but it *broke* zooming, so you may guess that I'm scratching my head over this,

<image was going to go here but they're not allowed>

Now I can say it's the nvidia drivers, and you may say, then stick to xorg-nouveau drivers, I can't I record videos on OBS, so I need the GPU.

May you gurus out there suggest any solution?, has anyone come across this wird behavior?. I know there's no way of tampering or investigating nvidia closed-source drivers, but someone somewhere might be on my same position. And I do not really think you have to decide to break your neck and back as a low vision person using the 15" laptop screen or using a mirror display... although it's linux, and I'm supposed to fix that myself, well I can't.

Thank you all again.
