Hi thanks a lot for your comment. It helps me know that the program don't bug for everyone. xD
I worked on a MUCH better version that run at 120 fps on my old 500$ PC ! So, that one frame delay will solve your first point.
If I understand correctly your second, I tested that. It was horrible when you scroll or minimize a window because it let boxes everywhere.
2d/hentai don't work very well, but I tested with a real woman standing and this seems to works. (butt and boobs) You had game mode off ? Anyway I plan to retrain a model with a better dataset.
I promise you to create a pixelate filter !
