Achievement frame freezing

[Haleth]

Hello.

I've noticed since patch 5.0.4 that scrolling through the achievement frame when there are many achievements listed, in particular the 'Lich King Raid' one (which is honestly a mess), seems to take up a lot of CPU as it often causes temporary freezes when scrolling quickly.

I've asked a few people but it doesn't seem to happen to them. I've got a decent processor though (Intel core i7 3.4GHZ) so that can't be a problem. I've turned off my addons too because one thing does seem to slow it down a tad more, namely hooking AchievementButton_DisplayAchievement, but it still happens without.

Does this happen for anyone else?
