Description Volga 2016-12-22 08:16:51 UTC 
Description:
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]

Actual Results:  
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.

Expected Results:
-


Reproducible: Always

Comment 2 V Stuart Foote 2017-03-09 01:33:51 UTC 
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.
