How to resolve Shearing issue while rotating image in Adobe After Effects? I had an image in my After Effect Composition. I want to rotate the image by time with out any disorder in its shape.

When I am trying to rotate image a shearing effect is happening. How to resolve this issue, so that there will not be any shearing to image while rotating.

Below I have attached what happening now when I am trying to rotate. 


Default Image : 0 degree rotation.

Transformed image : 42 degree rotation.
Make sure scale values are locked and set both to 100%:
