--- Comment #17 from Matthew Vaughn <nethershaw at gmail.com> ---
I've been following this issue since it was reported and I would like to
contribute if I can. Since the bug status is currently "NEEDINFO" I will
endeavor to provide corroborating details and offer my platform for
investigation and testing.

I can begin by validating everything discussed in the comments so far. The
issue presents itself on my platform exactly as Benjamin documented. My
platform only differs slightly:

OpenGL renderer string: Radeon RX Vega (VEGA10, DRM 3.26.0, 4.18.4-gentoo, LLVM
6.0.1)
OpenGL core profile version string: 4.5 (Core Profile) Mesa 18.2.0-rc4


The patches Timothy provided apply and build perfectly, and with the suggested
environment variables set while running NMS I can also exactly reproduce
Benjamin's result. World assets render correctly; the game is playable; the
galaxy map "clouds" are not visible; there appear to be significant artifacts
in the semi-transparent background textures of most UI elements (conversation
dialogs and the tab menu).

My first attempt at reproducing the problem and using the proposed patches was
done on Mesa 18.2.0-rc4 built from source, but I have no problem in principle
with testing further against the current 18.3.0 development branch.

I am happy to test additional patches and gather any additional information
upon request. Thank you for starting the work.
