From 8b50a9f00f6f5b693d18c59ff15968e2b902ebf8 Mon Sep 17 00:00:00 2001 From: Michael Brasser Date: Fri, 25 Jan 2013 21:00:15 -0600 Subject: Dereference the QImage once the corresponding texture is bound. We do not require a reference here, as the texture is only bound once. It is the texture factory that is reused (when QQuickWIndow::setPersistentSceneGraph(false) is set and the window is hidden and then re-exposed). With this patch it becomes trivial to create a custom QSGContextPlugin with a texture factory that does not retain the QImage, freeing up memory. This is useful in the case of an embedded system with only a single window that is never hidden or re-exposed.
