Screen goes black when switching to fullscreen in vlc or mpv

Hello,

I have this issue where, when playing any video on VLC or MPV, screen goes black if I switch to full screen mode. Audio is playing fine, and if I go back to windowed mode, video comes back after a couple of seconds.

I tried with Dragon player (same video file) and it is working fine.

Any idea on what could be the issue ? I have a nvidia card running on proprietary drivers.

Thanks
