UPDATE: GR finally stabilized itself.
Thanks
I made a new city.txt file, added it, after several modifications, and now GR is acting strangely. Animation has sped up, the map keeps shifting, and my first city config is flashing as the map changes (in blue)
See here:

Should look like this all the time
Thanks for any suggestions.
