I masked now Xorg in pacman.conf, but this only as a first workaround.

Any hints how to fix the issue are more then welcome. In which config-file I need to make modifications?

Re: [Solved] After update of Xorg to 21.1.1-2 DPI is wrong

I had the same problem today and fixed it by making my window manager execute the following command on login to set the DPI value manually:

xrandr --dpi $YOURDPI

Supposedly you could also try to find the command, your display manager uses to start xorg and add the -dpi option,
or create a config file for xorg, set your physical screen size in mm and let xorg calculate some DPI value based on that (which i think is very unintuitive, especially on a multihead setup with different screen sizes).

Upstream is reverting the change, for what it's worth.
