I've just upgraded from 12.04 to 12.10. For the most part, everything works fine, but I have a few small problems with Unity, or maybe Compiz.
When I hit the Super key, or click on the dash launcher, the dash sometimes comes up behind the other windows on the screen. As you can imagine, this makes it somewhat tricky to use.
Once it has started coming up behind, no amount of trying again will convince it to come back to the front.
Possibly related, the Alt-Tab switcher doesn't show either. It maybe that there isn't one, or maybe that's behind also? Alt-Tab does switch the windows, but there's no visual indicator.
When I hit Super-W, the windows do all do the zoom thing, but it's slow and juddery where it used to be smooth in 12.04.
I'm using the standard "radeon" driver, same as before, with a triple-head monitor setup (and that works fine). I've not tried the proprietary drivers as I've previously found the multi-monitor support much weaker than the default driver, but maybe that's the way to go now?
Video play fine. Even WebGL seems ok.
Do other see this problem? Is it a bug? Or have I just got some left-over config from 12.04 in the way?
