System: NetBSD doppelganger.waterside.net 1.4L NetBSD 1.4L (DOPPELGANGER) #1: Tue Oct 12 18:44:19 EDT 1999 email@example.com:/usr/src/sys/arch/i386/compile/DOPPELGANGER i386
problem happens on my laptop with Neomagic MagicGraph 128XD
I'm running the following:
screen 0: tail -f cvs-update-log (which was empty and not
screen 1: tcpdump -i ne0
screen 2: vmstat 5
At some point, I switched from screen 1 to screen 2 and noticed
that the *middle* of the screen contained data from screen 1.
Switched to screen 3 (empty screen with login prompt) and back,
but the "droppings" from screen 1 were still present on screen 2.
Screen 1 seemed to contain the right data.
It looks like screen 1 was in the middle of a scrolling action
when I switched screens.
