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.
