Compositor effects lag with NVIDIA graphic card

Hello.
today I had to format my pc and in the new installation the compositor effects are laggy.
In the live environment this does not happen.
I point out that I had also encountered this problem in the previous installation but I do not remember how I had managed to solve it.

Here is a video of the problem. The weird effect of the top bar is only in the video.
The place where it is most visible is on the latte bar.

UPDATE:
The problem seems to have almost solved itself after putting the same refresh rate on all screens and then putting it back up.
If you have any advice, however, they continue to be appreciated.

Different refresh rate on different screens tends to increase GPU workloads and even not only in Linux. For example see
https://www.nvidia.com/en-us/geforce/forums/game-ready-drivers/13/277945/dual-monitor-setup-with-different-refresh-rates-14/

So, it is preferable to keep same refresh rates on all monitors.

There continues to be a slight lag even with the same refresh rate on all monitors but it is not that noticeable
