Mh, logging isn't too useful just give us the output of the logs, please run this before doing changes from the control center
journalctl -b0 -ef /usr/bin/gnome-shell Then do the change from control center and give us what the has been logged. Also, the output for (before and after, if anything changed) xrandr --verbose Could you also check if the command: xrandr --output DVI-D-0 --scale 2x2 xrandr --output DVI-D-0 --scale 1.5x1.5 Does something for you?
