Multitap sequences (more than 2 taps) had a 180ms timer set only on press, not on release. New taps within those 180ms could either trigger multitap+drag or another multitap (for N+1 taps), resetting the timer on press once again. If no new tap appears within those 180ms, the sequence was considered complete. This behavior differed from regular taps: for the very first tap of a sequence the timer was set both on touch and on release. The multitap timing caused misdetection of triple-tap-and-drag sequences as the timer was hit frequently. Some of those were correctly detected, others as tripletap only. Changing the timer to be set on press **and** release gives us a more lenient timeout. 180ms for tap-and-drag and 180ms for the next tap down after release. This was also the behavior for the xorg synaptics driver. Note that quadruple-tap-and-drag didn't suffer from this because the timeout resulted in double-tap + double-tap-and-drag. Which has the same user-visible effect. |

libinput
libinput is a library that provides a full input stack for display servers and other applications that need to handle input devices provided by the kernel.
libinput provides device detection, event handling and abstraction to minimize the amount of custom input code the user of libinput needs to provide the common set of functionality that users expect. Input event processing includes scaling touch coordinates, generating relative pointer events from touchpads, pointer acceleration, etc.
User documentation
