With GLSL #version > 410 are not used the "*_glsl_410_core" shaders, but older ones

Hi @ocornut

Using ImGui_ImplOpenGL3_Init("#version 450");, I noticed that ImGui use and add the string #version 450 to the defaults *_shader_glsl_130 shaders , while I would expect it to use *_shader_glsl_410_core shaders.

It's not really a problem, it works anyway and the shaders are formally identical, but from source:

imgui/examples/imgui_impl_opengl3.cpp

Lines 480 to 484 in 2d363fa

	else if (glsl_version == 410)
	{
	vertex_shader = vertex_shader_glsl_410_core;
	fragment_shader = fragment_shader_glsl_410_core;
	}

would be enough just to change:

else if (glsl_version >= 410) 
 { 
     vertex_shader = vertex_shader_glsl_410_core; 
     fragment_shader = fragment_shader_glsl_410_core; 
}

or is there a particular reason why it is?

Thanks

No reason afaik. If you confirm that it works i’ll make the change!

[ocornut]

Applied the patch now!

Yes, I confirm: it works.
I tested and used it for a couple of days before to open an "issue".

Thanks.
