Bug ID: 91998
Summary: Object rendered completely black in The Book of
Unwritten Tales: The Critter Chronicles
Product: Mesa
Version: git
Hardware: Other
OS: All
Status: NEW
Severity: minor
Priority: medium
Component: Drivers/Gallium/radeonsi
Assignee: dri-devel at lists.freedesktop.org
Reporter: daniel at constexpr.org
QA Contact: dri-devel at lists.freedesktop.org
apitrace: http://constexpr.org/tmp/BOUT-CC-radeonsi.1.trace.xz (95 MiB)
The pipe behind the character is rendered completely black. The object is
rendered without any shader but with fixed-function lighting enabled.
Relevant draw call: 2336877 (in frame 1699)
Disabling GL_LIGHTING, GL_LIGHT3 or setting the GL_DIFFUSE material to [0, 0,
0, 0] (including alpha) causes the pipe to be rendered correctly. Disabling the
other lights has no effect.
The GL_EMISSION material is set to [1, 1, 1, 1] for this draw call so the other
lighting parameters should have no effect (unless they result in NaNs or
negative values).
GPU; Radeon HD 7950 (TAHITI)
Mesa 11.1.0-devel (git-0337a9b)
LLVM r247497
Linux 4.2.0-gentoo-r1
Everything is rendered correctly with llvmpipe.
So far I have only found one object in the game affected by this.
