Video call popup disappear on View Full Screen

I am facing the issue with the Mac book pro 15 inches screen. When I click the icon “Full Screen” from the video call popup, the popup moves to the end of the screen. It’s happening only on the Safari browser. What did I do to resolve this issue?

Not sure I understand, can you perhaps share a screenshot?

Thank you for your reply.
Please find the screenshots

You seem to be used some integration, where Jitsi Meet is part of a larger application. You’ll need to report it to that application in this case.
