Create a window by using gtk+3.0 or gtk4, and set the titlebar off. #include <gtk/gtk.h> int main( int argc, char *argv[]) { GtkWidget *window; gtk_init(&argc, &argv); window = gtk_window_new(GTK_WINDOW_TOPLEVEL); gtk_window_set_decorated(GTK_WINDOW (window), 0); gtk_widget_show(window); gtk_main(); return 0; } 2. Compile the program gcc -o hello_world $(pkg-config --cflags --libs gtk+-3.0) main.c 3. Run the program GDK_BACKEND=wayland ./hello_world OBSERVED RESULT A blank window with titlebar.
