This made me think that it was…

I remember in the early days of flat screen TV’s it being a thing (in the United States at least) that there existed 720p native displays on the low end but they supported input of 1080i at the very least to comply with ATSC regulations. I suspect what is going on here is that Kodi thinks your TV supports some display mode that it doesn’t and that is what is causing the screen tearing. You can keep running like this or if you wanted you could also make a whitelist excluding any problematic modes…
