Xrandr transform definitely broken in latest update

I am used to using xrandr to transform the screen proportion with an external projector. Specifically, I use the command:

xrandr --output HDMI1 --transform 1.378746,0.098137,-183.333333,0.136642,1.448562,-283.333333,-0.0001189455,0.000104,1.000000

This command applies the following transformation:

However, since xorg-server 1.20.13-3, xrandr is broken and the command “transform” basically doesn’t work anymore: bug report

Until now, I could still use the old version (1.20.13-1) but since the last update I needed to also update xorg to prevent a large number of packages to be uninstalled. Namely, I try to downgrade xorg-server, it asks to uninstall the following:

:: xorg-server and xf86-input-elographics are in conflict. Remove xf86-input-elographics? [y/N] y
:: xorg-server and xf86-input-void are in conflict. Remove xf86-input-void? [y/N] y
:: xorg-server and xf86-video-amdgpu are in conflict (X-ABI-VIDEODRV_VERSION). Remove xf86-video-amdgpu? [y/N] y
:: xorg-server and xf86-video-ati are in conflict. Remove xf86-video-ati? [y/N] y
:: xorg-server and xf86-video-intel are in conflict. Remove xf86-video-intel? [y/N] y
:: xorg-server and xf86-video-nouveau are in conflict. Remove xf86-video-nouveau? [y/N] y

Is it safe to uninstall them? Which other solutions could I use?
