+libXdamage incorrectly encodes/decodes the 'More' field from the event.
+
+The client library for xdamage currently fails to fill in the 'more'
+field. As a result, you get whatever uninitialised junk was there
+before.
+
+The server sets the high bit of 'level' when there is
+'more' (DamageNotifyMore = 0x80). A patch follows to fix the client
+library. (from GIT)
