NetBSD singbulli 9.99.99 NetBSD 9.99.99 (GENERIC) #134: Sat Sep 3 19:18:38 UTC 2022 root@keemun-b:/home/riastradh/netbsd/current/obj.amd64/sys/arch/amd64/compile/GENERIC amd64
>Description:
Normally, if I tap and then move my finger on the touchpad, it is as if I press a button and hold while moving my finger on the touchpad -- it grabs and drags, either moving a window or selecting text. Tap twice times and move, and it selects text by words. Three times, by lines.
In current, however, after I tap, once I put my finger down, the cursor freezes and doesn't move with my finger on the touchpad at all. If I lift my finger, the cursor unfreezes and I can move it again with a new touch, but it doesn't drag or select anything while moving.
Relevant dmesg fragment:

>How-To-Repeat:
Tap touchpad and quickly touch down and move finger.
>Fix:
Yes, please! I suspect this was probably broken in the synaptics rototills earlier this year.
