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

image showing the bad triangles

These triangles are not static, they flicker around the screen a fair bit

I am seeing the same with my vega64 on KDE Neon with the oibaf ppa.

packages are marked as 17.4~git1801200730.436ed6~oibaf~x

kernel: 4.15.0-041500rc5-generic

You can easily reproduce this by running the graphics benchmark.

I tried to capture an API trace but the game slowed down so much that the
benchmark did not get far enough along to show it :( 

(it is entirely possible that I am holding it wrong too)

Bug ID: 104602
   Summary: Graphical artifacts in Civilization VI on RX Vega
   Product: Mesa
   Version: 17.3
  Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
  Severity: normal
  Priority: medium
 Component: Drivers/Gallium/radeonsi
  Assignee: dri-devel@lists.freedesktop.org
  Reporter: zach...@gmail.com
QA Contact: dri-devel@lists.freedesktop.org

System is Arch Linux running kernel 4.15-rc7 with Mesa 17.3.1

When playing Civilization VI and zooming the camera out to view more of the
map, I experience a large number of black, flickering, triangle-shaped
artifacts across the screen. While this doesn't seem to crash the game (I'm
able to play for an extended period without the application crashing still), it
is distracting.

I've had this issue since switching to a Vega card from Polaris, running first
the amd-staging branch of the kernel, then the 4.15 RCs, and from mesa-git
through 17.3 stable. The game updated today and the issue is still present.

As far as I've noticed, no other game experiences the same bug, so I can't be
certain if the fault lies in the driver or the game itself. If needed, I can
attempt to capture some screenshots or video of the bug.
