The screen curruption that you are talking about, I am getting that in firefox 4 32bit version too, specially while playing flash video and with add-on/toolbar icons (both in unity as well as classic mode). This corruption does not happen with chromium. Also I was experiencing the sluggishness exactly the way you explained. At time titlebars in unity gets missing and I have to do compiz --replace which fixes the issue.
