I have a full screen frame. I switch between laptop screen only and external screen only using Windows key + P. The whole frame is redisplayed AFAICS. I tried a frame with one window buffer and a frame with 3 windows buffers. I have the feeling that it flickers more when there are more buffers displayed in the same frame. Albeit no definitive proof of it. I'll let you know if I have some reasonable clue about where to look.
