Some devices have worn-out switches or just cheap switches that trigger multiple button events for each press. These can be identified by unfeasably short time deltas between the release and the next press event. In the recordings I've seen so far, that timeout is 8ms. We have a two-stage behavior: by default, we do not delay any events but we monitor timestamps. The first time a bouncing button is detected we switch to debounce mode. From then on, release events are delayed slightly to check for subsequent button events. If one occurs, the releas and press are filtered. If none occurs, the release event is passed to the caller. https://bugs.freedesktop.org/show_bug.cgi?id=100057 Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net>
