Whenever I move the cursor relatively slowly, it's as if the game does not recognize the movement. The cursor itself moves flawlessly, but the game does not react to the new position until I move the cursor quickly. This occurs only in 1.3, with or without Ideology. Downgrading to 1.2 resolves this issue, but it reappears upon upgrading to 1.3 again. This is especially noticeable (and troublesome) when "painting" in the menus or trying to investigate a pawn's health conditions. I've chosen not to include a save file as this bug occurs everywhere in the game, even in the main menu.
