Hi-
In 4.5 and several 4.5 rcs, I see occasional stuck taps (I think) on
my XPS 13 9350's touchpad. The effect is that trying to left-click
ends up middle-clicking. I think it's a kernel issue and not a
hardware or libinput issue, but I'm not 100% sure. I don't think I
had this issue in 4.4.
I've attached what I think is an evtest issue of my fixing the issue
by pressing three fingers down in sequence and then releasing them.
After doing that, left-clicks worked.
