Touchpad stuck on click

Folks,

I have encountered a wired issue with touchpad: it stay in status similar to
pushed left button. I can move it, but I can't select anything.

If I make rigth click, it may clicks, or may ignore it.

I have no idea how to dig it, but it appears after move from 7.4 to
snapshot, and it's here for couple of weeks.

Hardware: Huawei Matebook X 2020

~ $ doas wsconsctl mouse
mouse.type=touchpad
mouse.rawmode=0
mouse.scale=0,3643,0,2000,0,31,31
mouse.reverse_scrolling=1
mouse.tp.tapping=1,3,2
mouse.tp.mtbuttons=1
mouse.tp.scaling=0.221
mouse.tp.swapsides=0
mouse.tp.disable=0
mouse.tp.edges=0.0,5.0,10.0,5.0
~ $

Rigth now it was reproduced on snapshot without any additional patches.

If you have any idea how to dig future, I'll appriciete that.

Thanks.
