Wine 8.12 console log

During the opening scene of a new game of Dyson Sphere Program on Steam there
is an unusual white triangle that clearly shouldn't be there. Indeed, it isn't
there on Windows 10.

Artefact: https://youtu.be/8pVK9s-a--o
Normal: https://youtu.be/7hXvhXKy9TU?t=272

I can't figure out what should be there instead. It looks to me like nothing.

Workaround:
"winetricks arial" (Bug 47325)

No demo that I know of.

VGA compatible controller: NVIDIA Corporation GK104GL [Quadro K5000] (rev a1)
(prog-if 00 [VGA controller])
Kernel modules: nvidiafb, nouveau, nvidia_drm, nvidia

Using the latest Nvidia drivers that support my hardware:
470.199.02-0ubuntu0.22.04.1

Tried setting the shader to "arb" but it made no difference.
Setting the shader to "none" upgrades the triangle to a full sphere surrounded
the ship, which is obviously not better.
