In geometry, the tesseract, also called an 8-cell or regular octachoron or cubic prism, is the four-dimensional analog of the cube; the tesseract is to the cube as the cube is to the square. Just as the surface of the cube consists of 6 square faces, the hypersurface of the tesseract consists of 8 cubical cells. It is not being distorted, reshaped, or anything like that. It is simply Rotating - It appears to be distorted because you are only seeing the ‘projection’ of it.
