3.2.5.2.4 Logical Surface Compositor Reference Order

Upon receipt of a TS_COMPDESK_LSURFACE_COMPREF_PENDING (section 2.2.2.4) message, the surface manager proxy SHOULD NOT release the proxy structure for the logical surface until the compositor opens a reference to it. This is to avoid releasing a logical surface before the compositor has a chance to get a reference to it, which could cause drawing artifacts.
