Resolved: Can't set TearFree on new AMD card

I'm trying to enable TearFree using xrandr on my new notebook with an AMD GPU. I have two displays enabled: eDP-1 and DP-1. On my old machine with an AMD GPU, I run

xrandr --output DP-1 --set TearFree on

and it works. On this machine though, I get this error:

X Error of failed request:  BadName (named color or font does not exist)
  Major opcode of failed request:  140 (RANDR)
  Minor opcode of failed request:  11 (RRQueryOutputProperty)
  Serial number of failed request:  37
  Current serial number in output stream:  37

Here is the xrandr output for this display:

DP-1 connected 3840x2160+1920+0 (normal left inverted right x axis y axis) 941mm x 529mm
   3840x2160     60.00*+  59.97    29.98  

How can I prevent tearing?

TearFree is a property of the xorg driver, is xf86-video-amdgpu installed?

xf86-video-amdgpu has no direct relation to the kernel module, a xorg.log would be more interesting/telling, can you setup a configlet? https://wiki.archlinux.org/title/AMDGPU … _rendering

I added a configlet and restarted X. Problem solved.

Thanks.
