Actually, I used xrandr to downscale. used Xft.dpi to tell clients to
about the DPIs. Normally it works in multiple of 96. So I specified 192
and then downscaled using xrandr --scale 1.25x1.25. This is to achieve
fractional scaling.

Will do.

When I used ‘sway’, I found it lighter. May be just a feeling of
something new. But I want to give it a try for some time.

Resetting everything else to default settings and just specifying

output DP-2 scale 2

in the ‘sway’ config file. It works fine except that now everything is
too big. Other GTK apps scale well. But Emacs without pgtk is
pixelated. How to achieve smooth rendering of buffers and the menubar
items without building --with-pgtk?
