I'm set up to use the "latest" repo, and installed the Update Pack 2, in it's entirety, yesterday.
I'm happy to report that even though I let it update EVERYTHING, (I unpinned everything I had pinned), my proprietary ATI drivers still work fine, and I can now even boot to the latest kernel without problem, something I hadn't been able to do before.
But, I have noticed one small problem. Now, when I move my cursor to the bottom right corner area of the screen, it sticks for a second or two. It will come "unglued" if I wait, so it's not that big of a problem, just annoying.
Anyone have any ideas how to resolve this?
