So as it says in the title I'm seeing strange behavior not see by me before todays Beta update, including 23.4 release. When I'm pancake editing and have overlays on and I play the sequence loaded in the source monitor opened in the timeline the external monitors screen goes black and only the overlay remains. When paused both overlay and picture shows in external monitor. I've looked into possible transmit problems, metal issues, gfx card, media cache ect. I'm no rookie. Thoughts?
