Hi ​@Filipov, Filip, apologies for the delayed response! To confirm, are you only seeing these black screens in the preview but not when you’re in the prototype mode? 

Have you had a chance to check if this happens in both the browser and the desktop app? That can help us narrow down the cause.

If you’re comfortable, could you share a link to your file and also invite support-share@figma.com as an editor? (This won’t affect your billing at all.) That way I can open the file on my end and see if I’m getting the same black screens in the preview.

Thank you for your help!
