MXIII-G 4K 2GB/16GB
LibreELEC-n200-AP6330_2G.arm-9.2.8.2 - some glitches at boot(when you see "linux things" - same with last snapshot but not important). Wifi no problem(connects with kodi repo straight away and is downloading skin without any issues), movie freeze gone. If there were no more changes from previous snapshot then i was testing it for hours and it is working flawless.
No volume/mute osd but i think it might be related to my avr/panasonic 4k tv but my older openelec build works without that glitch - will try to track it down with debug..
LibreELEC-MXIII-Plus.arm-9.2.8.2.img - no wifi for me so didn't test it more. Glitches at boot.
That glitch is normal, also present in M8S+, due to the framebuffer reset (by platform_init script).
However, this is necessary to correct the freezing error, but I think we can live with that.
Since you have a clone with the AP6330, the universal n200 image is basically the best (and perhaps the only working) choice.
I enabled the image as stable, thanks for your feedback.
