I downloaded Unity a week ago and started playing with it and today, after making a new project, the editor window started acting very strange in that even having only a blank project, the grid cannot be seen except from certain angles, and when loading some objects in the scene they are clipped in almost half of the lower portion of the screen and a bit to the right. Same thing happens now to any project that I load.
I didn’t mess around with interface settings or something like that, and except for downloading and installing the CityEngine Trial, there was nothing else I can think of that would lead to this behavior.
