Hi,

Thanks for the recordings, the precision of the touchpad seems to be excellent
with both gestures.

Can you try changing these lines in libinput/src/evdev-mt-touchpad-gestures.c
(around line 200):

        /*
         * Semi-mt touchpads have somewhat inaccurate coordinates when
         * 2 fingers are down, so use a slightly larger threshold.
         */
        if (tp->semi_mt)
                move_threshold = TP_MM_TO_DPI_NORMALIZED(4);
        else
                move_threshold = TP_MM_TO_DPI_NORMALIZED(2);

To:

        move_threshold = TP_MM_TO_DPI_NORMALIZED(2);

Then re-build libinput, install the new version and see if that solves your 2fg
scrolling problems?

Regards,

Hans
