Bug ID: 108794
Summary: Inconsistent behavior with Separable Shaders
(ARB_separate_shader_objects)
Product: Mesa
Version: unspecified
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: Drivers/Gallium/radeonsi
Assignee: dri-devel@lists.freedesktop.org
Reporter: epigr...@yahoo.com
QA Contact: dri-devel@lists.freedesktop.org
When running Cemu, (an OpenGL application under wine), it appears there is
inconsistent behavior with their feature "Separable Shaders".
a) When BotW runs, and SS is off, the "tent" of some Stables may be invariably
culled off the scene (along with a few other textures).
b) In contrast, when SS is on, it causes the lighting in some Shrines to be
oversaturated.
Hardware: AMD R9 290, Intel Haswell
Software: Kernel 4.18.19, latest libdrm, current mesa repo source, llvm 8 from
their site's repo for debian sid.
tl;dr: In any case, there appears to be inconsistent behavior on results of
separable shaders being used or not when the same methods seem to work on
Windows. I do not have access to the source of the test software to investigate
further and I have not debugged mesa calls further (and I probably won't).
