I am facing a very annoying behavior in Xubuntu, and I have been experiencing this since many versions (I think 16.04 is when I switched to Xubuntu) with many different computers so this problem has to be very common. Surprisingly I did not found questions/answers in Google about this so I ask here.
When I click/right-click the icons next to the clock in the panel the menu appears below the mouse pointer. Because of this, sometimes the option that appears just below the pointer is accidentally clicked (even by doing a single click) and this is very annoying. Usually this option is to close the corresponding app, but it can be anything. In this link you can see a video with the problem I have. I did not manage to make the apps to accidentally close in the video, but you see the "exit" button appears just below the pointer. Is there any easy solution for this? Like adding a constant offset to the menus, or adding a constant delay time of about 333 ms.

I had this problem when I tried to make the panel auto-hide until hovered. Had to give up on auto-hiding.
In panel preferences, set
Automatically hide the paneltonever, and uncheckDon't reserve space on borders.I remember having to log out or reboot for this to fix the issue on older Xubuntu versions, but it doesn't seem to be necessary on 20.04.
To me the problem was happening when using an extra monitor, configured above (not at the side). The panel was at the bottom of the above monitor, where this issue was happening.
When clicking the option "Span monitors", the panel would go at the bottom of the lower monitor, and then the context menu (when clicking something, like the bluetooth icon) would appear correctly on top of the main menu bar.
