Element Selection is Distorted, elements do not fit

I am using UiPath Studio on this machine since a year. But since today, selection elements is no longer possible.
The blue frames (while selecting elements) do not fit to the actual elements anymore. All the blue elements are smaller when selected with UiPath than in the real GUI.
At least, in the runtime it still works… the issue only happens when i try to select a new element.

Is there a workaround for this?
