This provides some sort of synthetic XSYNC support for unmanaged clients and allows them to do an initial update after mapping and before being painted (prevent flicker) Also it helps with Unmanaged clients performing quick map/unmap/map cycles what also seems to induce the black window issue on the nvidia blob.
