A clutter actor might be painted on a stage view with a view scale other than 1. In this case, to show the content in full resolution, the actor must use a higher resolution resource (e.g. texture), which will be down scaled to the stage coordinate space, then scaled up again to the stage view framebuffer scale. Use a 'resource-scale' property to save information and notify when it changes. The resource scale is the ceiled value of the highest stage view scale a actor is visible on. The value is ceiled because using a higher resolution resource consistently results in better output quality. One reason for this is that rendering is often not perfectly pixel aligned, meaning even if we load a resource with a suitable size, due to us still scaling ever so slightly, the quality is affected. Using a higher resolution resource avoids this problem. For situations inside clutter where the actual maximum view scale is needed, a function _clutter_actor_get_real_resource_scale() is provided, which returns the non-ceiled value. Make sure we ignore resource scale computation requests during size requests or allocation while ensure we've proper resource-scale on pre-paint. https://bugzilla.gnome.org/show_bug.cgi?id=765011 https://gitlab.gnome.org/GNOME/mutter/merge_requests/3 |
