Evolution Refresh(?) bug

Something refreshes periodically in Evolution and it causes everything to shift down for a split second. It's kind of a problem because it interrupts my reading, and I'll sometimes click the wrong thing if I happen to click at the same time as (whatever this is) refreshes.

I had this solved at one point, but I didn't write down the solution, and naturally forgot. This problem has cropped up again, and it's driving me nuts, so I'm bumping this thread.

You forgot to add how you installed Evolution.... Did you install EVO using a Flatpak or Snap or installed from the repo?
