--- Comment #106 from Mathieu Belanger b747xx@gmail.com 2009-06-10 08:47:08 --- I see in my old bug report on ATI unofficial bugzilla : http://ati.cchtml.com/show_bug.cgi?id=1462 that the problem has been fixed in internal Catalyst release near march 02. Post by pierre.boudier@amd.com also state that a latency of +- 3 months exist between internal and public release of catalyst! So this match with the hpestilence post about the bug fixed in the next cata version!
I will hunt for this Catalyst 9.6 and repost here if I find it!
