LibreOffice 5.3 is already allowed Mongolian ellipsis display proper vithin vertical text. But when I enabled OpenGL, the problem appearing again. Also, CJK double angle brackets are also affected.
Steps to Reproduce:
1. Enable OpenGL & restart
2. Open attachment 128631 [details]
Mongolian ellipsis is clipped as three dots. CJK double angle brackets are also clipped a half when I use Mongolian Baiti, but it can be avoid via Mongolian Baiti:vert=0.

For bug 103831, the removal of DirectWrite Direct2D calls for scaling glyphs with OpenGL and instead using GDI calls corrects this issue as well.
The clipping no longer occurs.
