It's very helpful to use a second screen for cropping a pic. Mostly if I do so I have a live-preview on my second screen but sometimes the screen is always one step back. This appears only if I use one of the 8 handlers. If I crop a pic with one of these handlers nothings happens after the first try. If I make a second change with one of the handlers the preview of the scond screen goes to the first change and so on.
Normally you can see every change live, but sometime not. Sometime a restart helps, sometimes not. So I really like to know what the problem is.

I get this problem frequently. I'm using Lightroom Classic CC 8.2 on Windows 10 (both with latest updates, though I think it has been doing the same for previous Lightroom versions).
The problem is most obvious with cropping (both dragging resize handles and dragging the picture within the frame), but also occurs with other options. For example, I just made an adjustment to shadows on the basic panel and the second screen was left behind.
When I make an adjustment, the change starts to be shown on the second screen about half a second afterwards, lagging slightly behind the main screen as I gradually drag the mouse. I think the bug may occur when the second screen has caught up, then I make a further change fast/small enough that it registers as a single mouse event. It gets shown on the main screen but is never processed on the second screen even after releasing the mouse button.
I have made a screen capture showing an example from moving the cropping resize handle.
