There is something very wrong here, it ends up in the "fetch from history" branch when I'm selecting something on screen. And the code is a bit wonky, the comment says that _screenLinesSize is the same as _screenLines.size(), but it doesn't seem to be always updated (in this case _screenLines.size() is 62, _screenLinesSize is 61). From trying to reproduce, it seems to be happening sometimes when resizing the window (so things get reflowed), and then double clicking on a highlighted URL. Can consistently reproduce by double clicking to start word selection, and then moving the cursor over an URL. A possibly relevant merge request was started @ https://invent.kde.org/utilities/konsole/-/merge_requests/562 Git commit 651ebc2ca600a1d2be91f994aebc1a720f06eea6 by Martin T. H. Sandsmark. Committed on 24/12/2021 at 17:18. Pushed by tcanabrava into branch 'master'. Work around weird position reported from filters.
