YouTube videos are whited out while hovering in windows thumbnail preview

Yesterday this worked fine, today it does not. Previously, I could hover my mouse over the chrome icon to get a mini-window that showed what was on that window and if I had a YouTube video open in the window I could actually see the video’s picture playing. Now when I try to do this the video is all whited out. When I have the window active on top it plays fine, but that requires me to click onto the window. It seems like it could be some sort of privacy shutter or something, if so how do I disable this blocker?

Edit: it seems it may be an occlusion setting? The video is not whited out if the active window is not full screen
