Crashes with dual amdgpu/nouveau gpus (amdgpu has 2 monitors connected)

hyprlandd.log
It seems to freeze on the TTY until I run pkill Hyprland via SSH. If I set AQ_DRM_DEVICES=/dev/dri/card1:/dev/dri/card1 it crashes with the following report:
hyprlandCrashReport347642.txt

AQ_DRM_DEVICES=/dev/dri/card1:/dev/dri/card1 is invalid you are duping the card

[theoparis]

Oh. Well it still seems to crash without any drm devices variable set 🤔

build aq in debug and get a debug stacktrace https://wiki.hyprland.org/Crashes-and-Bugs/#obtaining-a-debug-stacktrace

Oh ok - I didn't see that page, my bad.

open an issue in aq, get a debug stacktrace (bt -full not all, and this looks like a release build)
