Is it a bug? How to disable this window completely?

Normally the window has also the thumbnails/images.
Tested version PotPlayerSetup-1.7.13341 beta, also in previous beta versions, Win 10 64-bit.
EDIT: So if I just click Stop and then drag another video, Scenes window is always opened, but if I close the "Scenes" window with X button and then drag another video, it's not opened, but the, after some time, when I open PP few times, drag few items, then it's opened again, so it looks quite random, still.
