The resolution-based scaling may result in deltas of 0. The accel code doesn't handle 0 deltas too well. 0/0 deltas can't happen for EV_REL devices, so the code just isn't designed for it. Most notably, events with delta 0/0 have no direction. That messes up the history-based velocity calculation which stops whenever the current vector's direction changes from the one in the trackers.

libinput libinput is a library that handles input devices for display servers and other applications that need to directly deal with input devices. It provides device detection, device handling, input device event processing and abstraction so minimize the amount of custom input code the user of libinput need to provide the common set of functionality that users expect. Input event processing includes scaling touch coordinates, generating pointer events from touchpads, pointer acceleration, etc. libinput originates from weston, the Wayland reference compositor. The source code of libinput can be found at: http://cgit.freedesktop.org/wayland/libinput For more information, visit: http://www.freedesktop.org/wiki/Software/libinput/
