I am unsure whether checking whether the mouse was moved is the best thing.

I considered checking whether the cursor has ever been visible (e.g.
aura::client::WasCursorVisible() I couldn't think of a way of correctly
initializing the cursor visibility in CursorManager though. There are issues
with passing the initial visibility to the CursorManager constructor)

+      Shell::initially_hide_cursor()) {
+    // Do not move the cursor if the cursor has not yet been moved and the
+    // cursor is initially hidden. Moving the cursor generates a mouse event
+    // which shows the cursor.
+    return;
+  }
+
   // If the mouse is currently on a display in native location,
   // use the same native location. Otherwise find the display closest
   // to the current cursor location in screen coordinates.
