Looking for a way to create shapes with different... er... angles

I think the developer’s comment can explain it.

[major bug] Krita loses quality

Note that rotation will always lose some quality because of the pure fact that the pixels are organized differently to show the same image. But depending on which filter you choose, they might have better or worse results. Remember to not rotate things multiple times if you don’t have to. (You can adjust, but only as long as you’re staying in the Transform Tool, otherwise it will rotate it again and lose more and more quality with every rotation)

In krita 5, if you want to rotate an ellipse, like wojtryb said, make an ellipse and hold ctrl+alt before releasing your mouse or stylus.
