I finally tried out the images filter on hotscreen but noticed it pretty much sucks at censoring breasts. On the old censor app you had, it would place an image on each individual breast so it worked perfectly for different orientations, bouncing etc (even if the fps and delay left gaps the overall tracking was a lot better) and with a better variety of image shapes
With how hotscreen does it now, it uses a single image to try to cover both breasts at once, which for small circular images/icons it's functionally useless. This also means even with a big rectangular image, it doesn't work too great when there's just one breast showing, or the orientation is different from the typical flat side by side (i.e. someone turned horizontally on a bed or something)
