No, it's only in games. Video and GUI is fine.

Same issue with your build too. Side-scrolling games look jerky:
-
Interesting. I just built matrix/9b4db0e and glitches are still there. Can you upload your build?
-
Did anyone try retro gaming on my builds?
I remember there were no issues when I tried some Sega/SNES roms about a year ago.
With current Kodi master I get some serious texture glitches/stuttering. This is something specific to GBM/GLES as official nightlies don't have this issue. Tried to revert some GBM/GLES related commits but can't figure out when the issue started.

Any idea what the pros and cons are with the older drivers versus the new ones?
New Intel hardware e.g. Tiger Lake, Rocket Lake is only supported by the new media-driver.
For Gemini Lake and older I recommend to stay with "legacy" intel-vaapi-driver, at least for now:
On Gemini Lake VP9 10-bit videos don't play when using the new media-driver. I reported the issue here.

I'm not really sure about this. Last time I tested my gemini lake hardware enabled 12bit output.
I was talking about 50/60Hz 4K modes. 12-bit works with 2160p/24/30Hz.
-
On Gemini Lake 2160p60Hz is only possible with RGB 8-bit (default), YCbCr 4:4:4 8-bit (with a driver hack).
I'm not sure if YCbCr 4:2:0 12-bit could be enabled with a hack or otherwise. 4:2:2 is not supported by the driver.
It is possible to enable GPU dithering for 8-bit modes (with a driver hack). It certainly eliminates the banding on my test videos and looks ok to me.

Deinterlacing is not available when using your build
Switch off "Allow using DRM PRIME decoder" and VAAPI deinterlacing will be available. There is no other way at the moment.
But at the location on the screen where the subtitles should be, is a bar which contains a stretched version of the running movie but only the red portion.
Yes, I can also reproduce this on my Gemini Lake box. An issue with subtitle rendering.
-
The specs page say that it only supports 2160p at 50/60Hz. Maybe that is the problem?
-
My question; is it possible to install Libreelec (desgined for RPi 1/B+) on this board.
No.

I have not tested for long, because unfortunately the TVHeadend server on the build isnt working (requires a kernel-module which is not there - most likely due to the kernel-change?) and I needed to watch some TV
Yes, Tvheadend that was compiled for X11 version of LE doesn't work.
I compiled Tvheadend 4.2 and 4.3 that will work with my builds.

NUC6AYH has HDMI 2.0 port (MCDP2800 LSPCON), J3455 Apollo Lake SoC with Gen9 Graphics. It should be capable to support HDR in Linux.
Windows HDR support is irrelevant, Gemini Lake also doesn't support HDR in Windows.
-
and you cant roll back the update
In theory it should be possible with a Flashrom utility under DOS as long as somebody provides a bios dump from the same NUC.
-
Try to test with a short (< 2m) known good cable connected directly to a TV. Intermittent blanking in 4K modes could be caused by a bad or too-long cable.
-
the screen seems to go black intermittently for a few seconds and then the picture comes back on
Does this happen with all video modes or only with 4K?

NUC6AYH : No-go for HDR.
NUC7i3BN : Works with HDR (on the previous build you posted about roughly a week or two ago)
That's interesting.
According to Intel's support pages for those NUCs they use the same MCDP2800 LSPCON chip.
Can you retest NUC6AYH with the build from post #502?
Also note that there is an issue with those builds. If you turn the TV off and then on (while the NUC is connected and working) - HDR will stop working until Kodi is restarted (maybe a bug in EDID parser code).

You can install LE to a USB drive.
