This is a GTK Wayland back-end limitation. The window is made non-resizable via `gtk_window_set_resizable(GTK_WINDOW(window), FALSE)`. GTK translates this into the appropriate `_MOTIF_WM_HINTS`. But GTK itself doesn't actually send `set_max_size` to the compositor until it maps the surface, which happens later. But GTK3 on Wayland doesn't flush set_max_size to the compositor before the first commit regardless of when you call gtk_window_set_geometry_hints() on the application's code. GTK3's Wayland back-end queues protocol requests and only sends them at realize/map time, which is after the initial commit. The correct `xdg-shell` sequence must be: ``` get_xdg_surface get_toplevel set_max_size(w, h) ← constrain here wl_surface.commit() ← only then ``` Sadly I cannot report this to the GTK bugtracker myself. They banned me years ago, after (politely) complaining about how they just ignore user requests. Someone else needs to report this, and paste the link here. -- You are receiving this mail because: You are watching all bug changes.
