^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 111) IBM Trackpoints have a feature to compensate for drift by
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 112) recalibrating themselves periodically. By default, if for 0.5
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 113) seconds there is no change in position, it's used as the new
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 114) zero. This duration is too low. Often, the calibration happens
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 115) when the trackpoint is in fact being used.
