If you’re on macOS, the screen blanking is a known issue that’s happening because of some unknown interaction between the OS rendering and Emacs double buffering. IIRC, the mailing list thread about it concluded saying that nobody who wanted to work on the Emacs source had the requisite macOS knowledge to fix it and it’s been stuck there for a while?
