/sys/class/drm/card0/error

Interacting with a website in which a self-hosted potree.org visualisation is
shown. I can reproduce it by zooming and panning around, it is not happening at
a fixed location in the 3D space nor a specific interaction from what I can
tell. Website was opened in Firefox, display hanged, then resumed.

-- system architecture: x86_64
-- kernel version: 4.18.14-arch1-1-ARCH
-- Linux distribution: Archlinux
-- Machine or mother board model: FUJITSU.LIFEBOOK S936
-- Display connector: 3 screens:
eDP1 connected primary 1280x720+1920+0
DP1-1 connected 1200x1920+3200+0 left
DP1-2 connected 1920x1080+0+0

The browser window was on DP1-2 every time I had this happen.
