I can't say for sure, but the likely problem is that Kodi (or something else it's using) changes the HDMI resolution. The fbcp process (https://github.com/TheFlav/rpi-fbcp) that clones the HDMI output to the LCD can't handle on-the-fly HDMI resolution changes.
If you boot your Freeplay Zero/CM3 with HDMI attached and then run Kodi, do you see your TV changing resolution at the same time that the LCD stops updating?
EDIT: I didn't find a fix here, yet, but I was pointed to this thread on the topic. I'll add it here in case someone else wants to walk through it. https://www.raspberrypi.org/forums/viewt...&start=225
