There is one problem I have encountered with these builds that I have not been able to figure out - it has been present for all the Kodi 15 builds that I have tried.

No immediate idea, but we can perhaps narrow things down. Add to config.txt

Code:

hdmi_force_hotplug=1
hdmi_ignore_cec=1

and reboot, and see if it still occurs. That should mean the Pi is completely unaware of any power state changes of receiver/TV.
