I am using a HiDPI monitor with X11/GNU/Linux, and yes, out-of-the-box
rendering in that configuration is pretty accurately described by the
expression “mildly awful”.

I was able to achieve a non-awful result by customizing:

    (setq doc-view-resolution 192)

(to match my system’s idea of the monitor’s pixel density).

If you also want to use +/- keys to enlarge or reduce the displayed
page, you might want to set that higher than your actual DPI.

There is absolutely no reason to think only Mac users deserve nice
rendering in HiDPI configurations.
