Allow Flipping makes Dell S2721DGF blink with Driver Version: 515.65.01

I have a strange issue you can see here:

If I double click the top bar of my chrome browser my whole screen flashes black. I can reproduce it easily, it is not a one case occurrence. Reading a bit I’vw found some mentions as:
https://www.reddit.com/r/linux_gaming/comments/8gxhwf/nvidia_gaming_should_allow_flipping_be_disabled/

And decided to try it out, disabling it solved my issue. My question is:
What is going on here?

Which DE are you using?

KDE the latest stable branch.

Guessed so. IIRC, this is an issue of the kwin compositor that’s happening on some systems.

can you provide more info?

Not really, I only know it happens for some users.
