IDT algorithm has been fixed. There is a new parameter, Max Gaze Span, which determines the maximum possible gap between any two gazes in the window. By default it is set to 1000 - meaning that if a participant looks look-screen for more than 1 second, no fixation will "bridge" the off-screen gap. This also helps by allowing fixations that are close to the screen age still form, even if 1 or 2 gazes happen to wiggle off the screen.
The algorithm should be tested to ensure there are no longer any large fixations.
