> Sure thing: Thanks. The geometry values are consistent with what you described. This seems to be Bug#67654 and Bug#68463 and possibly Bug#65559. When you run Emacs from a console or under gdb can you observe whether it triggers a
gtk_distribute_natural_allocation: assertion 'extra_space >= 0' failed which typically means that the menubar cannot be accommodated. The one really notable difference to the above bugs is that the 29 version makes a shrunk frame only after you've removed the menubar while master makes a shrunk frame immediately. Are the GTK versions of the Emacs 29 build and the master build the same? > The window manager is mutter, I suppose? >> > > Indeed, yes. mutter doesn't like us. Just to make sure one thing: Would setting 'frame-resize-pixelwise' to t change anything? Otherwise I would try to build Emacs with gtk2, lucid or motif. martin
