Unagi Compositing Manager

I'm using awesome with focus=1/unfocus=0.7 config, and sloppy focus.

I opened 2 xfce4-term windows, w1 and w2. When i switch focus to w2, opacity changes as expected. When i switch back focus to w1, w2 disappears. I a switch focus to where w2 was, w2 appears and w1 disappears.

If i open a third window w3, and switch focus from w2 to w3, w1 is properly unfocused and w2 disappears. Then is a switch to w1 again, w3 disappears and w2 stays hidden.

Using xcompmgr these test cases work as expected.

Notice i get plenty of such warnings after the first switch, dunno if it's related:
