Or is there any precedence for this happening in other CIC's, I couldn't find any searching. Although it doesn't happen when I hit bumps, it seems completely random. Also it doesn't reboot after the flicker it just resumes where it was, so I don't think its a power issue, but maybe signal.

Any ideas?
You use a bad quality CAN Filter Activation module.
Flickering of the screen on the CIC is well known problem for some cheap CAN filters.
Contact with manufacturer and ask for the replacement.
It is not right when the manufacturer is asking you to solder the electronic components on board of their product to get the problem fixed.
