This only seems to happen with a few video files, so I'm sure it's more related to the videos and not kodi itself, but I can't find anything special about the video files themselves:
As you can see it detects the video as 23.809254 and sets the display refresh rate to 60, but 6 seconds in to playing it re-detects the video as 23.976 and sets the display to that.
mediainfo however reports the video as 23.976 with constant frame rate:
Any idea why kodi might be detecting the FPS wrong on this video file? or something else I could check on the video file to see why kodi might think it's 23.809?
edit: actually I've figured it out, it appears to be due to the MKV muxing:
