Wouldn't it make sense to set the default resolution to a value more
appropriate to the screen resolution then? I understand that someone
may want to change it for zooming for example, but OOTB seems quite
broken in a HiDPI screen and the average user (even the average emacs
user) probably doesn't understand a lot about scaling factors, not to
say about the existence of doc-view-resolution. Maybe now that there
is frame-scale-factor in emacs 28 it could be used to set the default
resolution for docview?
Best regards,
Carlos
