How to bypass the bug in VLC player motion detector?

Question

VLC

At some point, the player takes it for no reason and does the following:

motiondetect debug: Counted 10 moving shapes.
motiondetect debug: Counted 10 moving shapes.
motiondetect debug: Counted 10 moving shapes.
motiondetect debug: Counted 10 moving shapes.
motiondetect debug: Counted 10 moving shapes.
motiondetect debug: Counted 10 moving shapes.
motiondetect debug: Counted 10 moving shapes.
motiondetect debug: Counted 10 moving shapes.

That is, it produces a series of identical, abnormally high values.
At the same time, visually at this moment, he does not highlight anything.
That is, in what place of the screen he sees these movements it is not possible to find out.
Very similar to a bug. Perhaps the video somehow triggers this bug..
Where does this problem come from and what crutch can be used to fix it?
I put a blur on the video - it does not help.
and yes, the problem does not reproduce smoothly..
