I am not sure the issue come really from my code, cause it
just works fine on ATI cards, I do something Nvidia drivers

I tried to replace GL_LINE_LOOP by triangles, increase buffer

before glDrawElements without success.
Crash only append when I fill text mesh before those ones. So
I need dig more.
From what i saw in your code you are not using Vertex Array
Objects. I have had similar problems that code ran fine on ATI
but crashed on nvidia. The problem went away for me when i just
created and bound a global VAO just after context creation.
Also i would recommend calling glGetError after every call, it
helps finding errors. Here is a simple trick to do this
automatically.
static gl
{
static ref auto opDispatch(string name, Args...)(Args args)
{
enum glName = "gl" ~ name[0].toUpper.to!string ~ name[1 ..
$];
debug scope(exit) checkGLError(); //Do glGetError and log
it or something.
mixin("return " ~ glName ~ "(args);");
}
}
After this simply change all glFunctionName(args) to
gl.functionName or gl.functionName.
I will try the global VAO.
I already check glError with "checkgl!" function.
