I tested Blizz for the first time today. The following problem appeared. I have two computers. On both computers I installed Blizz and I optionally started a screen transfer from both computers. If I transfer the screen of the Windows 7 computer, the screen is transferred without problems. But if I transfer the screen of the Windows-10 computer, the area for recording, screen sharing and the controller bar are displayed on the computers of the participants as a grey field. When transferring from the Windows-7 computer, the screen is displayed completely.
