+Subject: [PATCH] Only create window handles for actual windows
+
+winId() creates a platform window for the given widget. This makes sense
+for the topmost widget in a tree, we can't assume the parent widget is
+the topmost widget.
+
+Doing this on XCB is confusing and wrong, but apparently harmless. Doing
+this on wayland causes issues as we promote the parent window to a
+subsurface but never show that window leaving things in a bizarre
+corrupt state that leads to content not updating.
+
+BUG: 445196
