Seems good to go, I used 2.4.4 and this FT_LOAD_FORCE_AUTOHINT in the call and
it worked. win7/64 bit.

Subject: Re: [opensource-dev] STORM-1090 : font size regression
Hi,
I received a very good hint from Ov Dos about this font rendering issue:
http://lists.nongnu.org/archive/html/freetype/2011-03/msg00010.html
I tried using FT_LOAD_FORCE_AUTOHINT (only 1 call to change in
LLFontFreetype::renderGlyph()) and it appears to fix the problem. *However*,
I'm
experiencing catastrophic freeze (no crash but the whole Mac is locked, hard
reboot only option) on log in or TP and a terrible frame rate when I manage to
log in. I can't see the relationship between that glyph rendering change and
logging in on a region and the SecondLife.log doesn't give much hint except for
an inordinate amount of:
WARNING: isFeatureAvailable: Feature RenderDeferred not on feature list!
Question: Has anyone tried FT_LOAD_FORCE_AUTOHINT on other platform than Mac?
Result?
Cheers,
- Merov
