I have an old (2014) NUC 2820FYKH with weak scalars. Most of my viewing is 720p but I watch the occasional 1080p movie. Therefore I run my Windows 7 desktop and Kodi GUI in 720p and let my TV upscale to 1080p. I set "Adjust display refresh to match video" to "On Start/Stop" so when I watch a 1080p movie, Kodi will switch to 1080p23.976 and it will look good on my TV. I've been doing this over many versions of Kodi. Also due to the weak GPU/scalars, I have to run in full screen (not full screen window).
On Kodi 18 (Beta 1 and latest nightly), when Kodi switches to 1080p23, the video is only showing in the middle portion of my TV. Since the display area is so small, I can only see the top left quadrant of video content and Kodi UI. Playback is smooth though, and pixels are showing 1:1. Software rendering has the same translation/cropping. If I use fullscreen window the translation and cropping problem goes away but playback is choppy (as expected for weak GPU).
I still have the the old Kodi 17.6 installation and with everything set the same (true fullscreen adjust display refresh to match video), switching to 1080p23 video playback from 720p59 UI still works. So the only variable here is the Kodi version.
The Intel display drivers are pretty bad (eg at some 720p refresh rates including 23.976, the driver will center the 720p image on a 1080p screen for the which is awful) so I'm wondering if maybe older versions of Kodi were better at working around the Intel display driver?
BTW, great job to the devs and requesters for the new resolution whitelist feature!
