To MacRumors: Please stop publishing the same article (the same video and screenshots) with every Beta release. It's enough to put a link to the article and to just report on what's new in this Beta release.
Be patient with this beta at first. After updating, just let it sit for a few minutes, open a couple apps and give it time. After 5-10 minutes the issue will go away.
I know *most* of you read the posts every week and have seen this stuff, but it's new to some, which is why it's included each time. Sorry, I know it gets repetitive with later betas, but I don't want to leave info out for people who aren't regular readers. We also generally like to have something ready to go so we can let you guys know about betas right away, which is why we update just after with notes rather than waiting to include them first. Hope that explanation helps.
