All of the sudden the Application Switcher's graphics breaks:

Restart does help, but became a nuisance. How can I kill it? Restart it?

UPDATE: Logging off fixed this.

UPDATE 2: I came to a conclusion that this is a result of a conflict in the display cached data.

I've removed your second question, if you want you can ask it again as a separate question. But since you no longer have this problem, the question might not have a definitive answer. –  Loïc Wolff Oct 26 '11 at 11:05
    
I'm having a similar issue. Here's a screenshot for further reference. –  alampros Dec 20 '11 at 17:28
    
Your other post to which you linked suggests that this isn't "all of a sudden" but rather in response to hot swapping monitors. If that is the case, please update this question, or combine the two into a single post containing all the information. –  Daniel Lawson Feb 23 '12 at 5:09

It's provided by Dock.app. So you could try osascript -e 'quit app "Dock"' or killall "Dock".

Thanks. I did try 'killall Dock' and 'killall Finder' -- no luck there. –  konzepz Oct 26 '11 at 8:57

Did you try to kill UIServer?

You can either try killall UIServer or find it on Activity Monitor and kill it from there.

Thanks; though it didn't seem to fix the problem. –  konzepz Oct 26 '11 at 9:46

What helps for me is choosing a new color display profile in preferences. Now the graphic corruption is gone for the app switcher.

You could reboot your machine, or log out of the user account and log back in. If the problem is not recurring, that might be your best bet. If this problem happens often, obviously that isn't a good long-term solution, but for a rare occurrence, that might work.
