Multiple shaders compiling

Renderer::updateGLResources()

.
.
.
const QVector<HShader> activeShaderHandles = m_nodesManager->shaderManager()->activeHandles();
for (HShader handle: activeShaderHandles) {
Shader *shader = m_nodesManager->shaderManager()->data(handle);
if (!shader->isLoaded())

{ // Compile shader m_graphicsContext->loadShader(shader); }

}

=======
This snippet of code is the cause of multiple shaders attempting to compile at the same time. On desktop it spits out a compilation error during runtime.
Sean has already passed you more details on the matter.
