I am using RawTherapee_dev_5.8-2945-g36f1300a6_20210523.
Just before I would rotate and crop the image - I placed an elliptic local adjustment along a nearly horizontal feature - a shadow in which I raised the lightness. The center spot was the default size and the ellipse was shaped to cover the whole shadow.
When I in Rotate then introduced an almost 45 dg rotation clock wise, the local contrast ellipse didn’t follow, i.e. stayed in it’s original position as a (now) highlighted ellipse.
