+Subject: [PATCH] wayland: Only schedule a single cursor location update
+
+If the cursor is updated multiple times before the state is applied
+on the surface, the newer signal handled would overwrite the ID of
+the previous.
+
+We can coalesce these calls and keep just the last value with the
+already existing signal handler, add a check to make sure we don't
+add a second signal handler if there's one pending already.
+
+Fixes (harmless) warnings like:
+
+clutter_input_focus_set_cursor_location: assertion 'CLUTTER_IS_INPUT_FOCUS (focus)' failed
+
+When a second handler would stumble upon already cleared data.
+Easily reproducible when a VTE widget has the IM focus, but there
+may be other cases.
