The display is mostly blank... and: Fourth, when switching screens, there is a brief flash of vertical stripes before the new screen comes on... Can we do something to make sure that this transition is clean? Either a completely blank screen, or ideally, no blank screen, but the new text appearing? There are issues w/ font loading and display switching w/ the vt_vga display driver... Environment: System: FreeBSD carbon.funkthat.com 11.0-CURRENT FreeBSD 11.0-CURRENT #2: Tue Aug 5 16:40:10 PDT 2014 jmg@carbon.funkthat.com:/usr/home/jmg/freebsd.p4/opencrypto/sys/amd64/compile/GENERIC amd64 kern.vty=vt How-To-Repeat: load a font (for #2) and then just randomly switch between vty's... Very randomly (it may take 10 or 20 tries) the console will not display anything.. If you switch away and back again, there will be text... Also, looking closely when switching vty's, there is "junk", in my case, vertical lines, that is displayed between the text of the two vty's... Fix: unknown.. -- You are receiving this mail because: You are the assignee for the bug.
