Ahhhh, that may be it, but I'm not entirely sure. What I will do on the next update is add that resolution (4K) as a catch, and that should fix it. I'll do some testing before I push it out.
Switching the scale may work as well, but I'm not entirely sure since I'm still stuck in 1080P-land myself. lol!
Thank you so much for this screencap! I will use this for reference.
