I didn't complain because I think you have more important issues to
address, but I spend half of my work day on gnome-terminal and waiting a
couple of seconds when switching windows or desktops is rapidly
annoying. And no, I can't replace it because it's configured for my
needs and I heavily use the tabs.
If the bug could be addressed in gnome-terminal, I can work with them on
Gnome's bugzilla, with any detail you could give to me.
For now, I use a branch with Maarten's patches from February the 12th.
Hervé
