Reproducing the issue is simple.
A) For the preview map, simply click New Game, then Generate Preview, then left-click-drag the map to look around.
B) For the tech tree, access the tech tree via whatever means (press T, or click the research button, it doesn't matter), select any technology that has enough items in it to generate a scroll bar on the UI (Optics, for example), and left-click-drag to move your view of the tech tree around. This jittering is not nearly as bad as I see on the map preview.
While I noticed this while running a fair number of mods, I disabled all of them and reloaded to test, and the issue is still present.
Here's a short video recording of the issue in question, taken with all mods disabled: And here's the log file from when I recorded the above video, since the "how to" post says to attach it every time: I figure this is probably not a huge priority or anything, but I also figured you guys would rather I report this than ignore it
