An example document for reproducing the issue
screencast: http://www.youtube.com/watch?v=zIy-1_DTNQU Reassigned to SBA. http://gsl.openoffice.org/servlets/ReadMsg?list=dev&msgNo=2171 ===== The phenomenon - glyphs disappear in certain conditions - has been also reported in the Japanese community. It seems to application neutral. Changing text direction from Left-to-right (horizontal) to Right-to-left (vertical) also makes glyphs invisible. The transparent glyphs seem to remain there. Action of moving cursor seems to work fine. Exporting the document with invisible characters into PDF format seems to work. The phenomenon can be observed with recent DEV300 variants on Linux. What type of information does help you look into it? ===== Lets try and rule some things in or out Does export SAL_DISABLE_CAIROTEXT=1 make a difference ? I cannot see your video, so at what point size does text disappear ? With "export SAL_DISABLE_CAIROTEXT=1", the problematic phenomenon has gone. Without the environment variable, in horizontal writing, Japanese characters appear in equal or less than 14.6pt; they disappear in more than 14.6pt. In the case of vertical writing, Japanese characters appear in equal of less than 5.5pt; they disapper in more than 5.5pt.

Let me see if I can debug it The nGlyphFlags |= GF_UNHINTED in vcl/source/glyphs/gcach_ftyp.cxx for CJK text causes this grief If the use fontconfig hints patch at http://qa.openoffice.org/issues/show_bug.cgi?id=64508 is applied then this problem goes away We could either apply that, or disable the cairo text stuff @cmc: thanks for debugging into this regression introduced by issue 85470. I don't understand yet why cairo would make glyphs invisible when their hinting is different? Yeah, I don't understand either. *** Issue 88973 has been marked as a duplicate of this issue. *** Aaargh... I overlooked the fact that the cairo-codepath ignores the "extended glyph flags", e.g. for glyphs in vertical layouts or when hints get disabled. Will be fixed in CWS vcl30stop2. block Fixed in CWS vcl30stop2: - the nohinting flag gets ignored now in the cairo codepath - in vertical writing mode the non-cairo codepath is taken for now Additional testing hints: - load the bugdoc and zoom in (see the original bug description) - enable Tools->Options->Languages->CJK - select "right to left(vertical)" in Format->Page->Page->TextDirection - add a mix of CJK+Latin+CTL characters -- for a font that natively supports vertical writing -- for a font that needs vertical writing support emulation @sba: please verify on CWS vcl30stop2 *** Issue 92278 has been marked as a duplicate of this issue. *** SBA: Verified in CWS vcl30stop2. *** Issue 90421 has been marked as a duplicate of this issue. *** *** Issue 90959 has been marked as a duplicate of this issue. *** *** Issue 90804 has been marked as a duplicate of this issue. *** *** Issue 92270 has been marked as a duplicate of this issue. *** This issue is closed automatically and wasn't rechecked in a current version of OOo. The fixed issue should be integrated in OOo since more than half a year. If you think this issue isn't fixed in a current version (OOo 3.1), please reopen it and change the field 'Target Milestone' accordingly.
