That looks a lot like what my first one started doing… 
It printed fine over most of the bed, but anything that took it into the rightmost side of the bed made it start messing up.
Before we get too “gloom and doom,” though, check this post for suggestions to make sure nothing’s messing with your gantry alignment: Gantry Alignment Issue
If all that checks out, then I’m guessing support is going to want you to print a “gift of good measure” on PG draftboard, one in the middle of the bed and one as far as you can get it to the right. Take screenshots of each in the bed after printing, and also photos of how each of them turn out.
Good luck!
