The root view was not adjusting it's bounds after device rotation.

ios/sdk/src/JitsiMeetView.m

 
         // Add rootView as a subview which completely covers this one.
         [rootView setFrame:[self bounds]];
+        rootView.autoresizingMask
+            = UIViewAutoresizingFlexibleWidth
+                | UIViewAutoresizingFlexibleHeight;
         [self addSubview:rootView];
     }
 }
