Description Matthew Francis 2014-08-22 02:25:48 UTC 
Observed on:
  Ubuntu 14.04 / LO master
  Fedora 20 / LO 4.2.6.2

(Fedora doesn't come with the Takao fonts, but they can be installed from
http://rpm.pbone.net/index.php3/stat/4/idpl/23803159/dir/fedora_19/com/takao-fonts-003.02.01-11.1.noarch.rpm.html )

At a zoom factor of 454-460%, 12 point TakaoPGothic vertical text disappears completely. See attached video and document


The state of vertical text in general isn't that great at the moment, so this could be another bug in that category, or just possibly something in fontconfig etc.

Confirmed in 4.2.6 and master that at 454% the text is invisible. This is a regression as this doesnt happen in 3.3.0.
