There's one behavioral change here. Before this patch, if
gtk-titlebar=false
we never created a headerbar. This explicitly contradicted the comments in the source, and the documentation forgtk-titlebar
imply that if a window starts out without a titlebar it can be brought back later with thetoggle_window_decorations
keybind action.After this patch, a headerbar is always created, but if
gtk-titlebar=false
orwindow-decoration=false
it's immediately hidden.I'm not sure how this interacts with the current SSD/CSD detection that seems to happen when running Ghostty on non-Gnome DEs so it'll be important to get #4724 merged (plus any follow ups) to enable more explicit control of SSD/CSD.
