Hi, We identified that moving from freetype 2.3.9 to 2.4.4 in viewer-autobuild2010 produces smaller text (roughly 10% smaller).
Looking into this this afternoon, I was able to narrow it down to LLFontFreetype::addGlyphFromFont(): tracing the glypth width and height in LLFontFreetype::addGlyphFromFont(), one can see that 2.4 sizes are almost always 1 pixel smaller in height and sometimes width than the same glyph renderer with 2.3. 1 pixel on a 10 pixel high bitmap explains why moving the UI sixe rendering to 1.1 in preferences sort of compensate the problem. The underlying issue as to where this rendering difference comes from is unclear. Searching the freetype release notes since 2.3.9 doesn't point to anything particularly relevant to this. Diffing freetype.h and ftimage.h is not bringing any useful information either, or at least, I haven't found any. If someone has any light to shed on this freetype issue, it would be very much appreciated. For the moment, the plan of record is to downgrade freetype to 2.3.9 though, clearly, this is not the best solution. Cheers, - Merov
