You can't "zoom in" much past 200% without the resolution becoming too coarse to tell much. Also, your second "triangle" has too many "blobs" of red/brown (representing data points) to make a call of that ilk. Robert was making no inputs during "2:12:33 to 2:12:43, around FL210". This is not a software flight control problem, this is a "pilot freaking out and playing whack-a-mole with the controls" problem.
The only time of appreciable "DUAL INPUT" was around 2:13:44 to 2:14:02, with Robert trying to get the nose down and Bonin sporadically pulling up.
At about 02:14:18, Bonin slams the stick back one last time, and hits the sidestick priority switch, locking Robert out. He makes no mention of doing this.
