issue #3 from:
If you have a second font loaded, there is a boarder from where there is
no text (as we don't do font scaling), and sometimes this border does not
get cleared and there is garbage...
System: FreeBSD carbon.funkthat.com 11.0-CURRENT FreeBSD 11.0-CURRENT #2: Tue Aug 5 16:40:10 PDT 2014 firstname.lastname@example.org:/usr/home/jmg/freebsd.p4/opencrypto/sys/amd64/compile/GENERIC amd64
Load a second font, like the provided gallant, and then switch between
vty's.. You'll see where there is a slight border where the text doesn't
reach to the bottom or the right side of the screen, and sometimes in this
border, there will be junk..
I believe this issue is fixed in HEAD and stable/10.
Do you confirm this?
