The Problem is that when I'm using different apps the menu bar contains the options of previous app in the background and the options of current app in the foreground. If I try to make a screenshoot of it, it becomes invisible so the only way to see it is by a photo using my phone. I have tried to kill the SystemUiServer and restart the system many times but it doesn't look different. It is a bit annoying.

Looks like image persistence.

Thanks a lot for the answer! It can be the problem, but I'm not sure. On the other hand, if I understand well what is written about image persistence on Apple displays, it is caused due to a long period with a fixed image on the screen. While in my case it happens after a very short time like open and close the tab. Also it happens only in the manu tab and only with the dark mode otherwise I don't see nothing like this. So can it appears due to a problem on my display or the solution is something else ?
You're welcome. Since the problem doesn't show in a screen shot it has to be a form of image persistence. If your Mac is older and/or you have the brightness turned up that could shorten the time before persistence occurs.
Someone else may have a different idea.
Thanks for the answer, changing the setting help as i said before, for example if i don't use the dark mode this effect is quite invisible but it persists. Anyway the fact is that only few weeks ago the menu bar was ok and now no, so I'm wondering about what can be a the problem. Also the problem is related only in this little part of the monitor.
