Regression in 1.15.1: Three/four finger gestures not working any more
Summary
Since the 1.15.1 upgrade in Fedora 31 testing, three/four finger gestures like swipes do not work any more. Only the very first e.g. three finger swipe in a session succeeds, every one after that just creates the following output in the journal:
libinput error: event4 - SynPS/2 Synaptics TouchPad: kernel bug: touch 1 ended and began in in same frame.Downgrading to 1.15.0 reliable makes it work again.
Unfortunately I was to late to add bad karma to the update on bodhi, so this no goes to stable :(
