<pre>Anti alias (GL_LINE_SMOOTH) does not work when drawing lines using Shader in
OpenGL.
As a result of our investigation, the context in which MSAA
(MultiSampleAntiAliasing) is enabled, Then It seems that the anti-aliasing will
work if you create it.
So the question is how could we make the anti-aliasing to work under MSAA
disable mode?
For your reference, if you use AMD driver to run it, The anti-aliasing function
works well even when MSAA is disable.</pre>
