Comment # 3 on bug 104602 from Jason Playne

So I was able to get an API trace of the problem!

(I am rather happy to now be holding apitrace correctly!)

it does weigh in at 1.5GiB compressed but it does show all the badly rendered
triangles and how zooming in stops them

it is available here: https://jasonplayne.com/share/Civ6.trace.bz2

I hope this is helpful
