Visual defects with resolution 5120x1440

Brief summary of the problem:

I'm not really sure how to define this issue, google has not been my friend in this instance.

So here's a picture: image

If I take a screenshot it looks normal, but I already tried with OpenSUSE Tumbleweed and latest Linux Mint, they both have the same issue.

This happens only when I set the maximum resolution 5120x1440.

How to reproduce the issue:

The monitor is brand new, while the computer has a few years on its back, I can try any version of software/drivers/settings you can advice. I don't know how you could reproduce it, but I'm happy to provide as many logs as needed.
