FYI, somehow my LDCad installation got borked. The program would only load in a tiny window in the top-left portion of the screen, and would not function properly after maximizing. I should have taken screenshots or a video.
All is well now after deleting "AppData\Roaming\LDCad" and re-installing the program. The edge lines show up now like they should.
