From: Arkdae To: bug-gnu-emacs@gnu.org Date: Sun, 03 Mar 2024 10:56:15 -0500 References: User-Agent: Evolution 3.50.4 MIME-Version: 1.0 --7533a17835ef5fcd31cc708ab1e37218fcd3341c7cff22bf5eb64014be00 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: quoted-printable Start 'emacs -Q'. Open a long document which is longer than can fit in the window all at once. C-x 2 to split into two windows. Drag with the mouse on the information bar with button one to shrink the bottom window a bit. Then grab the scroll bar in the top window and drag up. The cursor reaches the bottom. Then I slowly scroll one more pixel up and all of the text contents are repositioned with the cursor at the middle. The next pixel scrolled up keeps the cursor in the middle and corrects the text to where it should have been. Scrolling at normal speed causes flickering due to this, and when I am trying to follow my place to see where I need to get to, it is hard due to this shifting every half-page. Scrolling down does not shift the text in this way, and the cursor correctly moves to stay within the viewable area.
