In the second display, any pop-up window appears and when the pointer is moved, the window closes.
For example: firefox address bar, I start typing and the auto-complete shows a drop down (a pop-up window) with occurrences in my history, bookmarks, etc; when I move the mouse, the pop-up disappears immediately and I don't have a chance to click in one of the items of the list. If I click in the desktop or any other window in the first display, the address bar works as expected.
It happens with the panel, with any menu, any entry box in a web form in which firefox or chromium tries to show stored values, etc; and it's random (although it happens a dozen of times every day).

So it may be a different bug!
