Is this solved at all? As of today, I still see some pdf files -but not others (how to tell the difference?) rendering improperly in evince. When the text is selected, the text is suddenly smooth and nice; when deselected, it's all sketchy and rough. Also, many equations and punctuation chars disappear when selecting text (an entirely different bug, I assume). None of the above exist in kpdf.

Re: [Bug 26118] Re: Bad rendering (hinting) in Evince and Xpdf
It's not the same bug. The document you attached uses Type 3 fonts, which in theory are drawn using Postscript (not PDF) primitives, but in practice are just bitmaps. Ghostview and Acrobad do a fine job with these, but poppler-based readers don't handle them well at all. The issue being discussed here only pertains to Type 1 fonts. So, unfortunately, I'm afraid your best bet for non-atrocious rendering is Acroread (yech!)

Re: [Bug 26118] Re: Bad rendering (hinting) in Evince and Xpdf
For the record, the fix that works for me is to change the
#ifdef...#else...#endif block beginning at line 179 of file
SplashFTFont.cc as follows:
// if we have the FT2 bytecode interpreter, autohinting won't be used
// MS: actually, disregard bytecode setting, as it yields poor results anyway
// #ifdef TT_CONFIG_OPTION_BYTECODE_INTERPRETER
// if (FT_Load_Glyph(ff-face, gid,
// aa ? FT_LOAD_NO_BITMAP : FT_LOAD_DEFAULT)) {
//return gFalse;
// }
//#else
// FT2's autohinting doesn't always work very well (especially with
// font subsets), so turn it off if anti-aliasing is enabled; if
// anti-aliasing is disabled, this seems to be a tossup - some fonts
// look better with hinting, some without, so leave hinting on
if (FT_Load_Glyph(ff-face, gid,
aa ? FT_LOAD_NO_HINTING | FT_LOAD_NO_BITMAP
: FT_LOAD_DEFAULT)) {
return gFalse;
}
//#endif
[sorry if I don't generate a patch---I still haven't learned how to do
so...]
In other words, I force autohinting off if anti-aliasing is enabled,
regardless of whether or not Freetype was compiled with the bytecode
interpreted on (which, in Ubuntu, it is).
Notice that this compile-time checking that poppler does explains why
this bug is hard to trace. Even if you recompile Freetype without the
BC on, it still won't matter, as poppler is compiled against the
standard Ubuntu distribution with BC enabled.

Sorry, my fix was bogus. I checked the results with a TeXmacs-produced PDF, which apparently includes different fonts than what e.g. pdfetex does. The TeXmacs fonts look fine.

[Bug 26118] Re: Bad rendering (hinting) in Evince and Xpdf [FIX!]
I think I nailed it! First of all, the exact same issue arises in Edgy, which is what I am using now. However, it's easy to fix. Second, it's a poppler problem, not an Evince problem per se. See file splash/SplashFTFont.cc in poppler-0.5.4 (the Edgy version), lines 180 and following. This is where poppler loads glyphs for the splash output device; this code comes from xpdf, btw. Basically, there is a compile-time check to see whether freetype has the bytecode interpreter enabled; if so, IT IS USED regardless of whether anti-aliasing is on or off. Otherwise, no hinting is used if anti-aliasing is on. Again, this is a compile-time check. The problem is that, for most fonts used with LaTeX (but I'd say for most other fonts, too) it's best to omit hinting altogether. I fixed the problem by simply deleting the portion of the code that is triggered if TT_CONFIG_OPTION_BYTECODE is defined, and instead leaving only the section that is compiled if it is not. Rebuilding with pdebuild and installing with dpkg -i did the trick. Ideally, this should be a gconf setting, I guess.
