      Description

      I am going to render a simple triangle in the scene. When using the build-in GLSL and modifing the original fixed contents to my own, the qt reports a bug as follows. I am sure that i am right because the code works before. However, after i add new texts it becomes bad.

      I write the same code and using addShaderFromSourceCode, it works. So how to deal with this problem?

      QOpenGLShader::compile(Vertex): 0(2) : error C0204: version directive must be first statement and may not be repeated

          • Problematic Vertex shader source code ***

      #define lowp

      #define mediump

      #define highp

      #line 1

      ???#version 330 core

      layout(location=0)in vec3 aPos;

      ......
