We are setting mime data with a destroy notify on the cairo surface to get notified when cairo registers damage for the surface (in that case, it clears the mime data, calling the destroy notify). Unfortunately, the destroy notify is also called when we remove the mime data ourselves, which was not intentional. Use a flag in the window impl struct to ignore the callback when we are clearing the hook.
