A photograph of one of two external displays that were in use when the panic

Today's panic occurred whilst playing GeoGuessr <https://www.geoguessr.com/> in
Chromium, full screen. Space bar pressed and held after a click on the
on-screen blue arrow (to travel as fast as possible). 

On the second external display: nothing other than Teams in Firefox. 

Note: play in Chromium coincided with a kernel panic at least once before … for
what it's worth, I tend to avoid Chromium for activities such as this (I did
suspect that a panic would occur before I began play today).
