QEMU screen grab after exiting splash mode

vt(4) has nascent splash screen support - a compiled-in 2-colour bitmap of the FreeBSD logo. It is currently activated in boot -m ("mute") mode.

Some garbage is left on the screen when switching out of splash mode, as in the attachment.

I can't reproduce this issue with plain hardware. Is this specific to QEMU?

Confirmed, it does not happen on my laptop w/ vt_vga.
Comment 3 Ed Maste freebsd_committer freebsd_triage 2015-08-10 21:53:49 UTC 
I cannot reproduce this with the candidate fix in PR191564.
Comment 4 Marcel Moolenaar freebsd_committer freebsd_triage 2015-08-12 16:03:33 UTC 
This is believed to be fixed for everybody in FreeBSD -current as of today (revision 286667). Please test at your earliest convenience.
