When line-spacing is not nil, 0, 1, or 2, the calc mode home line appears to be several lines above the real home (with the exact value depending on the calc window size), forcing the user to scroll down after each to see the most recently-calculated value. This behavior can be avoided by setting line-spacing to one of the aforementioned values in the calc buffer via calc-mode-hook In GNU Emacs 25.2.2 (x86_64-pc-linux-gnu, GTK+ Version 3.22.21) of 2017-09-22, modified by Debian built on lgw01-amd64-050 Windowing system distributor 'The X.Org Foundation', version 11.0.11906000 System Description: Ubuntu 18.04.1 LTS Configured using: 'configure --build x86_64-linux-gnu --prefix=/usr --sharedstatedir=/var/lib --libexecdir=/usr/lib --localstatedir=/var/lib --infodir=/usr/share/info --mandir=/usr/share/man --with-pop=yes --enable-locallisppath=/etc/emacs25:/etc/emacs:/usr/local/share/emacs/25.2/site-lisp:/usr/local/share/emacs/site-lisp:/usr/share/emacs/25.2/site-lisp:/usr/share/emacs/site-lisp --with-sound=alsa --without-gconf --build x86_64-linux-gnu --prefix=/usr --sharedstatedir=/var/lib --libexecdir=/usr/lib --localstatedir=/var/lib --infodir=/usr/share/info --mandir=/usr/share/man --with-pop=yes --enable-locallisppath=/etc/emacs25:/etc/emacs:/usr/local/share/emacs/25.2/site-lisp:/usr/local/share/emacs/site-lisp:/usr/share/emacs/25.2/site-lisp:/usr/share/emacs/site-lisp --with-sound=alsa --without-gconf --with-x=yes --with-x-toolkit=gtk3 --with-toolkit-scroll-bars 'CFLAGS=-g -O2 -fdebug-prefix-map=/build/emacs25-jYekUr/emacs25-25.2+1=. -fstack-protector-strong -Wformat -Werror=format-security -Wall' 'CPPFLAGS=-Wdate-time -D_FORTIFY_SOURCE=2' 'LDFLAGS=-Wl,-Bsymbolic-functions -Wl,-z,relro'' Configured features: XPM JPEG TIFF GIF PNG RSVG IMAGEMAGICK SOUND GPM DBUS GSETTINGS NOTIFY ACL LIBSELINUX GNUTLS LIBXML2 FREETYPE M17N_FLT LIBOTF XFT ZLIB TOOLKIT_SCROLL_BARS GTK3 X11 Important settings: value of $LC_MONETARY: en_US.UTF-8 value of $LC_NUMERIC: en_US.UTF-8 value of $LC_TIME: en_US.UTF-8 value of $LANG: en_US.UTF-8 value of $XMODIFIERS: @im=ibus locale-coding-system: utf-8-unix Major mode: Calculator Minor modes in effect: ido-everywhere: t override-global-mode: t evil-snipe-override-mode: t evil-snipe-mode: t global-undo-tree-mode: t shell-dirtrack-mode: t evil-mode: t evil-local-mode: t tooltip-mode: t global-eldoc-mode: t electric-indent-mode: t mouse-wheel-mode: t file-name-shadow-mode: t global-font-lock-mode: t font-lock-mode: t blink-cursor-mode: t auto-composition-mode: t auto-encryption-mode: t auto-compression-mode: t buffer-read-only: t line-number-mode: t transient-mark-mode: t Recent messages: Loading debian-ispell...done Loading /var/cache/dictionaries-common/emacsen-ispell-dicts.el (source)...done Loading /etc/emacs/site-start.d/50dictionaries-common.el (source)...done Loading /etc/emacs/site-start.d/50latex-cjk-common.el (source)...
