im getting this too, im even getting it without restarting, it always happens when "Passed" is on the screen and wont go away, its pretty unplayable as its happening every single puzzle im in
Getting the exact same bug. Got it on the cow puzzle, and now I'm getting it on the Traheaern var Vdyffir fight as well.
Game has been out long enough for bugs like this to get fixed. Disappointing.
