Jitsi Goes White when a User enters a Meeting

I am using a CefSharp Browser in a VB.NET Application where multiple users automatically Navigate into a Jitsi Meets meeting. I have one user whose screen goes white when he tries to enter our meeting. He can enter the meeting when he Joins through a Chrome Browser, and all works properly. Obviously the issue is in CefSharp, I am hoping others might have experienced such a phenomena? Any ideas would be helpful.
