Jiggling Desktop

[halk]

Something that has never happened before I upgraded to Lion. Occasionally whatever is on my desktop, including an open Safari window jiggles. The left side of the desktop shows a little section of the Dashboard. This last only for a second and happens every so often. No set pattern to the timing.
It's like my desktop has a nervous twitch.

That's exactly what's supposed to happen. OS X has been doing this for years. It means you didn't enter your password correctly.

Sometimes it will go for hours before I get the quirk. I never know when it will happen.

Do you use a magic trackpad or a magic mouse? Since you mentioned the bit with Dashboard, it seems to me like you're inadvertently swiping to the left, but not enough to actually move to Dashboard so you get moved back to the desktop, which produces the "twitch"...

I'm using a magic mouse. Sometimes it happens when I'm not touching the mouse, like when I'm watching a video or reading a document.

I think I solved this problem myself. I unchecked Show Dashboard as a Space in Mission Control in System Prefs.
