Comment # 8 on bug 1190646 from Takashi Iwai

Thanks, that's an interesting information.  There has been a recent update of
xf86-input-libinput, and it might be that.

Could you try to revert xf86-input-libinput package to the older version 1.1.0
and check whether the problem persists?  The old package should be available in
TW history repo,
