Whenever a MetaSurfaceActor is painted, update the list of what outputs the surface is being drawed upon. Since we do this on paint, we effectively avoids this whenever the surface is not drawn, for example being minimized, on a non-active workspace, or simply outside of the damage region of a frame. DND icons and cursors are not affected by this patch, since they are not drawn as MetaSurfaceActors. If a MetaSurfaceActor or a parent is cloned, then we'll check the position of the original actor again when the clone is drawn, which is slightly expensive, but harmless. If the MetaShapedTexture instead is cloned, as GNOME Shell does in many cases, then these clones will not cause duplicate position checks. https://bugzilla.gnome.org/show_bug.cgi?id=744453 |
