Here, whatever I do, with the window, it takes:
seq 100000 0,12s user 0,13s system 53% cpu 0,480 total
more or less.
But if I open another tab, the time grows:
seq 100000 0,26s user 0,23s system 26% cpu 1,796 total
That's the only thing I can say.
Do you have compositor deactivated in xorg? In xfwm?
