  Yea, they come from libinput and should only be relevant in Wayland session. Not sure about the effects stuff though. To test simply try touch input in Wayland session on client content and window decorations (tapping, dragging windows). If everything works as expected there should be no problem. I mean on the other side you can spot pretty easily in the reverted patch what the issue was there: `m_touchId` is sometimes -1 but gets casted to uint in the comparison.
