I don't have the issue, there are some marks (mostly on my roll bar's sport design paint which seems very prone to scratches) but nothing new since I have owned it that I am aware of and I have noticed no issues. I have never heard of the roll bar being different for the seats either, but I have included some pictures so you can see what mine looks like everything you see is stock on this car (except possibly the stereo if it in the shot). The last image shows my seats regular position when I am driving.
If the seat is not all the way back can't imagine how it would happen. You mentioned you replaced the seats, perhaps there is something about the way they were put in??
