I just created a new game and whenever a participant connects to the map and zooms in/out, it's nauseating and causes excessive stutter. Btw, it does not do this when using the Map View zooming in and out in the game. Also, the host never sees this issue, just the connected players, no matter how good/bad their latency is to the server. I had another player host on LAN, and when I connected to them, I experienced the graphical issues. Not sure if this is a known issue or indirect result of other mods I have loaded.
My current map is K2+SE using the Beta branch of Factorio , v1.1.x.
Visually, it's almost as if it's double-zooming, like two mechanisms are trying perform the zoom in/out operation and it results in contention.
