▪︎VFSG (Variable Frequency Starter Generator)
Yes, that shaft shouldn't wobble like that.
The wobbling is because this input shaft is broken.
The input shaft has a 'shear section'.
This means that if the VFSG (Variable Frequency Starter Generator) for some reason resonates out of limits or completely locks up, the VFSG input shaft breaks (controlled).
And the VFSG is disconnected from the accessory gearbox.
This prevents that the whole accessory gearbox locks, which results in failing of critical engine components (hydraulic pump, fuel pump etc.)

▪︎why does the curser jump from corner to corner but not to the center ?
The reason why it can jump from corner to corner is because the touchpad on the cursor control device (CCD) has hot spots on each corner where at the center there is nothing.
These hot spots allow you to quickly move up and down when you’re at the maintenance pages or doing a checklist as most options are on the top and bottom of the page.
If you look at the video again, notice that at the beginning the cursor is at the center and by pressing the lower left corner the cursor jumps and when I move back to the center I have to lift my finger a few times. You will find that the touch pads on most planes will operate the same way
