When I stop displacing my fingertop over the trackpad, the mouse pointer will not stop immediately. During one or two seconds (at most) it will continue to slow down to a halt, usually about 5 to 10 screen pixels further.

The same delay can be noticed when starting a slow (or short) movement. My finger is moving but the pointer remains at it's place, seemingly waiting for some minimal fingertop displacement before actually starting to move.

This all makes the finer mouse actions VERY hard. Trying to grab a window border (for resizing) for example is nearly impossible!

I did a firmware upgrade from https://github.com/ayufan-rock64/pinebook-pro-keyboard-updater

I've tried all different touchpad settings (acceleration, sensitivity, threshold) and tinkered with synclient parameters as described on https://wiki.pine64.org/index.php/Pinebook_Pro#X-Windows_.26_trackpad_tuning 

Also tried different OS images including Chromium from SD, all suffer the same touchpad issue.

Is there anything solution?

I followed the steps you mentioned, and it has massively improved the trackpad! The delay is still visible, but now it is usable after all.
Thanks a lot!

Ok, well, I guess I'll have to talk to support then. It is really annoying like this...
