Draftsight Quirky Display of Lines in Blocks

I've recently been seeing this issue with multiple computers / installs. Here is a link to a youtube video of what's happening https://youtu.be/0WyqEkuXtEU

(much easier to show than describe) but essentially lines appear / disappear based on cursor movement / zoom level. It SEEMS to be happening to lines in blocks but I can't say for certain that it is constrained to only that. That does appear to be the case however. As mentioned this has been happening recently on at least a couple computers here. The video is from a fresh install (6/13/22) on a new computer with the specs in the attachment. There should be no issue with hardware / computer.


Any thoughts?!? Is anyone else experiencing this as well?
