fix(shader): Disable frosted glass - OpenGL 3.3 core profile incompatible with fixed-function

Browse Source 
The issue is that imgui-bundle uses OpenGL 3.3 core profile which doesn't
support glBegin/glEnd. The shaders require VAO setup which is failing.
This needs proper OpenGL debugging in the imgui-bundle context.
