I can really reproduce this. On this other box, when the first window is
opened, I get like 1 second. Then retry, still 1 second. I open another tab,
try there, and get 2 seconds (wich is strange, I agree). Then retry in this
tab, and 1 second.
Same thing if I open another window.

If I maximize the window, it's more like 6 seconds (wich is a lot but doesn't
really surprise me)

Unmaximizing, it's back to 1 sec.

Opening 8 tabs doesn't change anything. First run is 2 sec, latter runs are 1

Can you try to reproduce with gnome-terminal, too?

As a side note, I'm using "fake" transparency (I can see the desktop trough
the terminal window, but only the desktop)
