Thinkpad T440s Touchpad Jumping Cursor (custom-made touchpad)
A bug occurs when using my touchpad in which the cursor will suddenly jump across the screen. I've been unable to replicate it until now. What's weird is that it seems that libinput is detecting the touch jump and attempting to discard it. In fact, after using
libinput debug-gui, I noticed that the first detected touch jump is actually discarded, only subsequent jumps are performed.
I've put up with this issue for quite a while and it's not a pressing problem, so if anyone could point me in the right direction / to the right file, I have time to attempt fixing it.
Place your thumb on the bottom left hand corner of the touchpad and click / scroll anywhere else with your index finder.
