After some more research, it turns out this is a pretty well-known
problem on the Linux desktop (it's called HiDPI) without a good
solution... except for this:

The solution is to patch xrandr with the capability to do nearest
neighbor filtering and run xrandr like this:

xrandr --output eDP1 --mode "3200x1800" --scale "0.5x0.5"

It works great.
