apitrace of Citra trying to compile that fragment shader
“Mesa 10.7.0-devel implementation error: Failed to compile fragment shader: FS compile failed: Register spilling not supported with m14 used”
In the attached apitrace, the fragment shader in question is at 1320.
Or alternatively, at https://github.com/citra-emu/citra/blob/master/src/video_core/renderer_opengl/gl_shaders.h#L66
probably same issue as with bug #86469
I can confirm the commit linked in bug 86469#c16 fixed Citra’s huge shader as well, thanks!
