Take a slider let go within a centimetre of the glass edge as its end, because the panel loses a finger swiped off the screen before the slider's end (0.2.80)

Browse Source 
A fast swipe off the right side of a Guition ended at 93-98 %: the GT911 reports the finger for the last time 33-48 px inside the edge while a wide tile's slider ends 29 px from it, and LVGL keeps the last point it saw. cyd::edge_snap() takes a release inside the band (SLIDER_EDGE_SNAP_PX: Guition 67, CYD 56) as the end that lies in that band, for the tile sliders and the light card's sliders; the log names each snap. App 0.2.80, firmware 0.2.67.
