One quick question, does removing the 'flat' modifier from both vertex and fragment shaders fix the linker error on your machines? |
|
|
Yes, removing all "flat" from shaders 140, the crash stops happening. I have a crashing computer available with AnyDesk with Noesis and VS available. If you want to access it, just let me know and I'll send you anydesk credentials. |

I got another crash on the same hardware, I remove the "flat" from shaders, and when I open the Gallery, Media and Brushes, a new crash without stacktrace happens. gallery - brushes - crash.png (261,875 bytes) |

Thanks for the offer for AnyDesk. I need to investigate a few things before. If you remove the "flat" keyword only for the fragment shader, does the linking error message disappear? Regarding the second crash, could you please check buildig everything in Debug? |

I removed the flat from fragment shader only, and crashs continues. If you want to check, this computer is dedicated for you test now. Anydesk ID: 514 240 482 Password: jsantos* Thanks. |

I am connecting to the computer right now! Thank you! |

Thanks for your help, I fixed the compiler error for the next version. This is the patch:

The crash in the gallery is really weird and there is definitely something wrong in the intel drivers. The problem is with the ConicGradientBrushShader, I just simplified to something like this:
static const char* GLSL_CONIC =
R"(
//float T(int n)
//{
// return cbuffer1_ps[4 + 8 * n];
//}
vec4 GetCustomPattern()
{
return vec4(1);
}
)";
And it works, but if I comment out the T() function the driver crashes (although T() is unused). I haven't found an easy workaround for this, so for now, we are not going to fix it, as this is not part of core. |

The shader related fix worked. I just tested it and everything seems correct. opengl has some weird things that are hard to explain... About the gallery problem, it seems to be a driver problem. Thanks for the quick correction. |
