Subject: bug#42406: Mouse-wheel scrolling can be flickering

Mouse-wheel scroll and then suddenly release the mouse-wheel, so that thereafter the text scrolled still moves for a short time. During that time, the text flickers.

(In case this is platform-dependent, I use the NS-port of Emacs 27.0.91/pretest)
