Hi, first of all thanks for the quick answer. Although we know that mainstream browsers are employing process separation I don't like the idea of relying on such feature for correct execution. The FreeType FAQ (http://www.freetype.org/freetype2/docs/ft2faq.html) asserts that the library is currently completely thread safe, so I assume the issue does not come from FT. Could you please explain (or link to relevant documentation) why pango is not thread safe? I'm interested in working to fix the issue and such information would be really useful. Thanks a lot, Alessandro Pignotti On Sunday 15 May 2011 23:11:24 Behdad Esfahbod wrote: > On 05/15/11 15:41, Matthias Gehre wrote: > > Hello everybody, > > > > I have a question regarding the status of thread-safety in pango. > > I found an old thread announcing some work on that aspect, > > but I could not find any confirmation of that it is actually safe > > to use it from multiple threads now. > > > > To clarify, we have the following scenario: > > We develop an NPAPI plugin, which we want to use pango for text > > rendering.
