Problem in the free hand box

Hi people! Could someone help me?

Since the last update, when I use free hand drawning, to make a handwriting in the document, or even a small simbol, the box stay too large. What is the problem? If I want to highlight a word or want make another simbol, cause the box are is too large, automatically it opens a edition box, as I show in the print screen here.

Could help me?
