Only happens when I set Kodi to my second monitor, both my monitors are 1080p and I verified they are both in 1080p resolution when this happens. TV (the one shown) is at full native mode, so it is not cutting off the screen for whatever reason they do that, you can see that it properly lines up in the top left. This is on 17 beta 2, and I believe I had the same problem in v16, and years ago when I briefly tried Kodi when it first came out. Since then I have changed GPU (currently 980 Ti) and I believe upgraded PCs.
