I am using Guake since 11.04, and I like it very much, it's my default terminal. Obviously I am using it's transparency option.
Because I haven't paying too much attention to it, I am not sure if the default transparency should be. Should it make all the background window transparent and show me the desktop behind? Or should it be transparent only to the first application It has open in the background.
I ask this question because I have noticed in the past week both situation happen on my Ubuntu 11.10 install. So right now I am puzzled about how it should be. And because it shouldn't behave different from day to day, I am suspecting Guake not be fully compatible with Unity.
I attach a picture of how I have it now, transparent to the desktop through Chrome and Nautilus
Edit: I have just looked at Guake homepage on this screenshot.
I can clearly see that the transparency should not go until the desktop, but it should show the first application it has in the background.
Edit2: Killed Guake and restarted it. The transparency works ok now:
