  1. It is a known issue that the Evince Document Viewer does not support subpixel rendering.

    Do a Google search for evince subpixel rendering.

    The explanation

    Well, actually the problem is not that patches are not good enough,
the problem is that it's not possible to enable subpixel-hinted
rendering without breaking transparencies. For subpixel-hinted
rendering to work we would need to first fill the surface in white and
then call poppler_page_render to render the page, but PDF blend modes
need an initially transparent surface to work. We consider blend modes
more important than subpixel-hinted rendering of fonts.

    There are patches to use to enable subpixel rendering. It is possible to apply them, even if you are not a programmer.

    In any case, subscribe to the bug report at https://bugs.launchpad.net/poppler/+bug/80921
