Camera Raw - Upright tool super laggy

Hi there,

i've already posted this issue a few months ago. Unfortunately the latest updates didn't solve the problem: I am using Camera Raw for my Architecture work on a daily basis. One of the most important tools is the "Upright" function. Since a few months this function is completely out of control and super laggy.  The magnifying glass and the drawn lines are not moving synchronal with the movement of my mouse. There are massives lags! Any ideas how to solve this issue? I am working on an iMac (Retina 5K, 27-inch, 2017) - macOs Catalina 10.15.7.

Would be thankful for some advice.

Best regards
