ingame game object is pixelated but in editor it is ok.

In the editor, the game object looks ok but when I run it in-game the whole game is pixelated I am putting every sprit in-game canvas which has a render resolution of 1280*720. that also renders with the camera. the camera is in perspective mode and it has a 1000 far and .3 near; plus can anyone tell me how to add screenshots here.
