ViewPortOut stopped working, it crops instead of zooming

I’m using two monitors, the HDMI-1 monitor has a bit lower resolution than 1920x1080, so for a few years in the config I was using ViewPortOut to zoom out the desktop/screen so it fits the monitor.
For some time (I’m not able to provide the exact time, probably a month) the ViewPortOut stopped working as before.
The testing command:
nvidia-settings -a CurrentMetaMode="HDMI-0: 1920x1080+0+0, HDMI-1: 1920x1080+1920+0 { ViewPortIn=1920x1080, ViewPortOut=1000x500+48+27 }"
instead of making the screen fit in the 1/4 of the monitor, it just crops.
Expected: in the upper-left corner of the monitor I see a zoomed out, full desktop, and the rest of the screen is black as expected
How it is now: in the upper-left corner of the monitor I see the upper-left part of the desktop, just as it would like without being zoomed, and the rest of the screen is black as expected
I’m using an up-to-date Arch Linux with pacman -Q | grep nvidia
lib32-nvidia-utils 460.39-1
nvidia 460.39-6
nvidia-settings 460.39-1
nvidia-utils 460.39-1
I would greatly appreciate any tips or help.nvidia-bug-report.log.gz (398.7 KB)

Please try adding an offset to the viewportin, like
ViewPortIn=1920x1080+0+0

Thank you for your help. Unfortunately it doesn’t change anything.
Used command: nvidia-settings -a CurrentMetaMode="HDMI-0: 1920x1080+0+0, HDMI-1: 1920x1080+1920+0 { ViewPortIn=1920x1080+0+0, ViewPortOut=1000x500+48+27 }"
