When the text direction is "right-to-left (vertical)" (vertical layout), Writer won't accept any key input at all, and on each key stroke, the displayed area flickers a bit.
To enable vertical layout, you need to
1. check "Show UI elements for East Asian writings" in the Options dialog (Language Settings - Languages, under Enhanced language support), and
2. go to Format - Page, and change the text direction from "left-to-right (horizontal" to "right-to-left (vertical)".
Once done, try to type any characters, it won't be accepted.
I was busy doing a bisect for another bug. I have now Version: 126.96.36.199.alpha0+ Build ID: b993c5591e965de3b9e95e32007ea4231b2997d (build of 2013-04-29 08:44:59), so if I can reproduce it with current (latest master version now), we have a quite narrow range. I'll try to post my findings after I build the latest master now.

-> I did NOT reproduce this behavior with that version.
looks like http://cgit.freedesktop.org/libreoffice/core/commit/?id=69c52bc5b7973a2e414209470f5bf9b66dcc4f30 broke this. perhaps some x in there should be a y
Caolan McNamara committed a patch related to this issue.
It has been pushed to "master":

Affected users are encouraged to test the fix and report feedback.
Ah yes, sorry about that. I needed it primarily for some debugging -- when I need it next time, I'll do it in smaller chunks and will definitely test vertical layout. ;-)
