 ------------------------------------------------------------------------------
 
 libinput relies on the caller to call **libinput_dispatch()** whenever data is
-available on the epoll-fd. Doing so will process the state of all devices
-and can trigger some timers to be set (e.g. palm detection, tap-to-click,
-disable-while-typing, etc.). Internally, libinput's time offsets are always

+available. **libinput_dispatch()** will process the state of all devices,
+including some time-sensitive features (e.g. palm detection, tap-to-click,
+disable-while-typing, etc.).
 
-For example, a touch event with time T may trigger a timer for the time T +
-180ms. When setting a timer, libinput checks the wall clock time to ensure
-that this time T + offset is still in the future. If not, the warning is
-logged.
+If the time between the event and the call to **libinput_dispatch()**
+is excessive, those features may not work correctly. For example, a delay in
+touch event processing may cause wrong or missing tap-to-click events or
+a palm may not be detected correctly.
 
 When this warning appears, it simply means that too much time has passed
-between the event occurring (and the epoll-fd triggering) and the current
-time. In almost all cases this is an indication of the caller being
-overloaded and not handling events as speedily as required.

 The warning has no immediate effect on libinput's behavior but some of the

+AlpsPS/2 ALPS DualPoint TouchPad jumping to 4095/0
+------------------------------------------------------------------------------
+
+A special case of pointer jumps happens on ``AlpsPS/2 ALPS DualPoint TouchPad``
+devices found in the Lenovo ThinkPad E465 and E550 and likely others with
+the same touchpad hardware. On those devices, the touchpad occasionally
+sends an event for the second finger to move to position 4095/0 before
+moving back to the original position. libinput detects this movement and
+removes it but depending on the interaction this may cause a smaller jump
+later when the coordinates reset to the new position of the finger.
+
+Some more information is available in `Gitlab Issue #492 <https://gitlab.freedesktop.org/libinput/libinput/-/issues/492>`__.
