VLC jumps back to main monitor

[an2net]

Hi!
I have the following:
Windowns 10
VLC 3.0.4
Laptop and Projector, Extended Desktop

VLC player control is on my laptop and the videos are playing full screen on the projector. There are about 10-15 music videos on the playlist.

Problem: The videos play perfectly fine on the projector, but certain videos (I assume lower quality ones) will "jump" back to play on my laptop, then I have to press the Windows, Shift and side arrow to send it back to play on the projector.
I have tried getting better quality videos, but is is not possible to get every video better, since some is old videos, which I must play.
What can I do to stop the videos from jumping back to the laptop?

Can you post some verbose logs to see what's going on ? There's a chance a different vout is used or a different codec between the files and a new vout is created from scratch.
