On a 118 cycle map I can pan the camera smoothly, even when the map is revealed by debug mode, example.
Every newly generated map (10/10 or so) has the camera stutter once larger parts of the map are revealed, example.

Using the seed from "Not a Game.sav" to start a new map has the new map stutter as well.
I tried this without mods as well, same problem.
Found an older (March) save "Dump.sav" that I never played. It does stutter!
Made a new game for a small (unrelated) test. Started with stutter after activating debug, but got smooth at some point. I only removed a small block to do my test, usually only removing 50%+ off the map "fixes" the stutter.
Added files "Labratory.sav" (stutter) and "Labratory Cycke 2 - Kopie.sav" (no stutter).
Letting the stuttery save run and/or redoing the previous test did not reproduce the "fix".
