Description Michael Stahl 2014-05-06 13:48:20 UTC

for this bugdoc from bug 70666:
https://bugs.freedesktop.org/attachment.cgi?id=87870

the rendering changes quite substantially when the Nonprinting Characters
button is pressed: letters disappear, and the diacritic marks below the
red letters disappear or move around.

the problem happens at least since OOo 3.2, got worse in LO 3.4 - LO 4.2,
and appears somewhat less bad on master (only diacritics disappear),
so i'm not sure to what extent this qualifies as a regression...

I can reproduce the problem only with an explicit SAL_GRAPHITE_CACHE_SIZE:

Tested with the attached file (a reduced version of the file sent by Gellért Gyuris).

export SAL_GRAPHITE_CACHE_SIZE=512
soffice # bad
export SAL_GRAPHITE_CACHE_SIZE=
soffice # good

Warning! The Graphite extension set SAL_GRAPHITE_CACHE_SIZE in the .profile under Linux. (I had a lot of problems with it, reporting a few false alarms to Martin, because I didn't know about it.)

Gellért found a similar SAL_GRAPHITE_CACHE_SIZE definition in his old .profile, (he used the Graphite extension and its cache settings). His newly installed Linux has no Graphite problems.
