I see the same issue with : Xcode 15.3 (15E204a) on MBP 16-inch, 2019 (2,6 GHz Intel Core i7 6 core) running macOS Sonoma 14.4.1 (23E224) with non-admin user as soon as I execute a SwiftUI app on a Simulator with iOS 17.2

1) I've the same issue, using TextEdit v 1.16 (364) in Big Sur, with a jump to the first line of the huge document, after a delete/paste of lines. No cursor is visible. As workaround, I use the "arrow down" as soon as it jumps to the first line of the document, and cursor moves back to the original page, one line below the position where I was before the delete/paste action. It means the cursor was still in the correct position, but the visible page was the top page, instead of current page. 2) Furthermore, if I try to use cut&paste, and selecting a lot of lines I request TextEdit to execute a scroll down, then my document seems to be corrupted, truncated, even if it isn't, as I can see closing TextEdit and opening document again. As workaround, I copy&paste only a visible lines, and save changes immediately. Please Apple, fix it asap !!
