@Nafi - a vsync issue, perhaps? Is this with all video formats, and have you tried disabling deinterlace as a test?

Yes, this issue exists with all content. The content played while recording the video was 1080p24, so no deinterlacing needed. Tv properly switched to 1080p24 resolution.

I'm really not sure.

How far back did you go with your testing of older Kodi 19 builds? Assuming it works on Gemini Lake, if you can test #0416 (which is the first Kodi 19 build in this thread) then if that has the issue it would be worth going back through the older Kodi 18 builds - in total there should be 365 builds (or thereabouts) still online, which is about 6 months of Kodi 19, and 6 months Kodi 18. Try bisecting these builds to help narrow down when the issue is introduced (assuming it's not present with the oldest available build which - at the time of writing - is #1001 [20181001]).

Are there any other Gemini Lake users with this issue when using these LibreELEC test builds?

Edit: I guess you should also make sure you're firmware is the latest - see this post in case it helps.
