I think this commit has introduced incompatibilities with xrandr. First, device name are changed (but maybe this is feature?). Second, my xrandr --transform commands don't work with xorg-server == 1.20.13-3 but work with xorg-server <= 1.20.13-1. What happens with the new version is that the transformation on the upper-left corner is wrong (hard to explain by words... I use the following script for my projector: xrandr --output HDMI-1 --transform 1.378746,0.098137,-183.333333,0.136642,1.448562,-283.333333,0.000117,0.000104,1.000000

You use Intel or a Nvidia card? Both patches are part of Debian and Ubuntu.

Sorry, somehow I had no notifications for this. I have no GPU, only the integrated Intel GPU.
