Description epigramx 2018-11-19 15:42:56 UTC

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).
