Bugzilla Bug 118728

when playing nwn, seemingly at random the 3d part of the graphics will be
replaced by a flat colour. often the compass goes black too. temporarily fixed
by saving, exiting to main menu and re-loading the game.

as stated at
http://nwn.bioware.com/forums/myviewtopic.html?topic=461888&forum=72 , the
problem occurs when anything step-changes the system clock, such as ntpdate or
ntpd correcting a drift too high to "slide".

solution: disable ntpd and/or ntpdate cron jobs, etc while playing nwn until a
patch comes from upstream

I've added a note to the end of the ebuilds pointing to both this bug and the
upstream forums.  If an actual fix comes about for this, feel free to REOPEN
it, otherwise there isn't anything that we can do about it.
