sounds like a hw-problem. I use also fw 107 with the Zidoo X6 Kodi-version and have no such problems you described.
my only problem at the moment is:
1. I use a 4K TV (LG 79UF8609)
2. if the H8 is set to 2160@60 booting to the Android-GUI is ok.
3. a first start of Kodi then results in a black screen, TV says no input signal after a few seconds.
4. switching off and switching on again the TV brings the started Kodi-Gui back. As an alternative
I can change the resolution with the H8-remote -> Kodi-gui appears, TV and H8 are in sync
5. If the H8 is configured other then 2160@xx (1080/720/..) then everything is fine, the Kodi-GUI
appears at once. It is not a matter of the fps, but of the 4K-resolution.
6. This behaviour is with the original Kodi from fw 107 (10-NOV-2015) and the Zidoo X6-Kodi
7. With fw 106 and before (older Kodi versions) this behaviour was not present.
Any advice?
