+*** Resizing frames of GTK Emacs does not work on Wayland running on X11.
+
+This was reported with KDE Plasma, which recently is based on Wayland
+exclusively (as is GNOME).  The default character-wise resizing of the
+frame depends on whether the window manager is willing to process the
+hints provided by Emacs; evidently, Wayland-based window managers no
+longer do.
+
+One workaround is to customize frame-resize-pixelwise to a non-nil
+value.  Another workaround is to add a window rule in KDE Plasma's
+System Settings (under "Window Management->Application settings for
+Emacs->Size and Position") that forces KDE Plasma to obey geometry
+restrictions.
+
+Yet another solution is to use the PGTK build of Emacs, which works
+better on Wayland.
