Hi Mark, thanks for adding a screenshot. This issue is unfortunately already on my To Fix-list. I have not find a way yet to fix this. As you probably know, it is not game breaking or gameplay affecting however. Do you play full screen or windowed?
hello Mark, I could not fix this. It is part of a plugin I am using and I do not know how it works. When you change the size of your layout/window a little bit, the blue line should disappear (or appear again).
