The current approach makes use of - A tiled rendering to work around gdk_texture_diff only doing pointer comparaison - Assumes that we would only recieve a scanout cmd followed by multiple flush ones In reality, with virtio-gpu at least, the scanout cmd is always submitted followed by a flush one containing the damaged region. With the assumption currently made, we end up creating a new paintable for every scanout cmd causing a full redraw instead of only redrawing the damaged areas. Isntead we create the paintable once and call import whenever we receive a flush cmd (UpdateDMABUF) so we can properly pass the damage area when creating a GdkGLTexture making the tiled rendering no longer needed.
