With the vendor provided Nvidia driver there is a small window of time after drawing to a GL surface before the updates to that surface can be used by the compositor. Drawing is already coordinated with the compositor through the frame synchronization protocol detailed here: https://fishsoup.net/misc/wm-spec-synchronization.html Unfortunately, at the moment, GdkX11Surface tells the compositor the frame is ready immediately after drawing to the surface, not later, when it's consumable by the compositor. This commit defers announcing the frame as ready until it's consumable by the compositor. It does this by listening for the X server to announce damage events associated with the frame drawing. It tries to find the right damage event by waiting until fence placed at buffer swap time signals.
