Have your tried increasing your browser’s Zoom settings to see if the inverse of the matrix will be larger for you?
You only included a screenshot and so it isn’t easy to test.
Similar thing with the wrapping. I have some ideas, such as perhaps adjusting line wrapping, but I cannot test since you don’t include the code. Although I don’t know if Sagemath also exposes the full range of customization current Jupyter offers?
And there is an ask sagemath Forum where you may get more pertinent information perhaps?
