Here with a GTK-3 build on XFCE disabling menu-bar-mode makes both frames smaller by the menu bar height. Does this happen on your system? >> C-x 52 ; window opens much smaller than initial window >> >> With master HEAD (commit 92ea393a16e), the situation is slightly different: >> >> Run: emacs -Q >> C-x 52 ; window opens much smaller than initial window In all these cases after every single step please evaluate (frame-geometry) and post the results here. The window manager is mutter, I suppose? Thanks, martin
