2d sprites border blurring while moving

Hello! I try to make 2d game and fight with quality. My sprites have borders. Some of that borders hides and some appears depending on screen position like in example. Where top border of right sprite is blurring. Thank you.

ps. I use ex2d, ortho cam 640, no mipmapping, no antialiasing. Point or bilinear filtering have same effect.

if you are trying to make a 2d game you will have to make sure that all your graphics are on different levels or they will begin to cross over each other causing the images to flicker and show some parts and not others
