Strange, I’ve never seen this before. I would definitely say a software issue.. and you are right, something to do with the new line. Maybe a terminal setting?
When you are using PiScreen, I assume you have a keyboard directly connected? And is it within a terminal that is running inside of X windows?
If you use HMDI, do you get the same issue on the HMDI output?
I would offer to try and replicate the problem myself, however I know nothing about Gphoto2.
