Comment 180 for bug 729979

Hmmm..

Just updated compiz and unity with Sam Spilsbury's ppa https://launchpad.net/~smspillaz/+archive/compiz-experimental?field.series_filter=raring

Now the blank black windows don't appear (for applications with multiple instances in use but minimized) with the alt tab switcher provided the applications don't open to full screen. So suppose I have multiple pdf minimized and I try to select one of them with alt-tab, if I focus on an instance which opens to full screen I still see the blank blackscreen. But if I choose an instance which opens to a smaller window then it is normal.
