the api QParameter ::setValue is work well in debug mode but not well in release ,QT5.10.1?

Hi,
Please provide a minimal compilable example that shows the behaviour.
Also, on what platform does that happen ?
-
ok by further test, i found debug mode also have probability of happening this issue.
this is snipset.
//fragment shader
#version 130
#extension GL_ARB_gpu_shader5 : enable
uniform highp vec3 cameraPosition;
uniform mat3 modelViewNormal;
uniform mat4 projectionMatrix;
uniform mat4 inverViewMatrix;
uniform struct LightInfo {
vec4 position;
vec4 direction;
vec3 intensity;
} light;
uniform int modetype;
uniform struct LineInfo {
float width;
vec4 color;
} line;uniform vec3 ka; // Ambient reflectivity
uniform vec3 kd; // Diffuse reflectivity
uniform vec3 ks; // Specular reflectivity
uniform float shininess; // Specular shininess factor
uniform int meshtype;
uniform float m3DObjectstatus[4] ;
uniform uint AppCurstatus[12];
out vec4 fragColor;
void main()
{
fragColor=(m3DObjectstatus[0] /255.0,m3DObjectstatus[1] /255.0,m3DObjectstatus[2] /255.0,1.0);
fragColor.a=254.0/255.0;
}
i will capture fragColor by QRenderCapture.and the uniform "m3DObjectstatus" is initial like this
m_3DobjectinfoParameter = new Qt3DRender::QParameter();
m_3DobjectinfoParameter->setName(QStringLiteral("m3DObjectstatus[0]"));
m_3DobjectinfoParameter->setValue(QVariantList() << 0.0 << 0.0 << 0.0 << 0.0 << 0.0);, but when i setValue again in somewhere ,but the value is not work for fragment shader .and the value of uniform "m3DObjectstatus" keep zero. -
Again, please provide a complete minimal compilable example that shows the behaviour.
