Log Message:
Bump rev for patch for this problem (from freedesktop.org GIT):

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.
