Public bug reported:
When using my Magic Trackpad with up to two fingers all works fine, like
scrolling and right clicking. As soon as I barely touch the pad with
three fingers, it becomes unresponsive for around 20 seconds. Checking
evtest, the same event is sent all the time, blocking all others.
evtest output after touching with three fingers:
