If nobody responds it isn’t because they don’t want to help but because no one else is having the same problem. I’ve posted many “bugs” here that no one else had, and with my new PC I’ve discovered all of them disappeared. I think Adobe software doesn’t play nice with every configuration out there, leading to all of these one off problems.
Hopefully I’m wrong and someone will come along with a solution (I read your other post as well) to your problems. As for me, I have one odd behavior in that if I put a transparent image on a timeline above a background and shrink it down, when I scrub the timeline the image appears at full size. It doesn’t encode like that but it makes it hard to see if it’s placed properly in frame. Just another example of adobe weirdness.
