Revised version of "Fallback to cairo's original LCD filtering if freetype lacks the capacity"
Ok, I've discovered the problem for my issues. Referring to a patched version of master, On line 1431 of src/cairo-ft-font.c it tests against the variable ft_can_filter. However, this variable is only initialized on line 1367 if it's performing subpixel antialiasing, otherwise it's always false. It ends up using the internal glyph rasterizer, while it has everything set up for the external one. Moving the line 1431 testing block to the top level fixes the problem, with the addition of an extra line to put FT_SetLcdFilter back to normal.
Attached is a version of the patch with said changes made. While I was modifying it, I noticed that there are some tab/space formatting issues with the patch that might need to be cleared up.
