No, they don't. But I think that, when compiz freezes, they continue responding, but for some reason, compiz (or Xorg, I don't know) doesn't update they're windows. When the windows become gray and Compiz is still responding, the windows respond, but when I hover an item on the launcher, it responds, but immediately compiz freezes and everything stops responding.
But the script that checks memory/CPU usage is run on a terminal: if it really doesn't respond, the process would be frozen too. But it doesn't, so everything is due to compiz, I think...
Sorry if I repeated too many times "but", but I'm not English nor American and I'm still learning it ;)
