How severely does this bug affect you?:
Steps causing the bug to occur:
- create new shader
- attempt to view vertex shader
Have you found a workaround?:
Fragment shaders share variables with the vertex shader, and are part of the same program. A vertex shader needs to be viewable, if not able to be edited and created, for functional GLSL coding. There are also code efficiency issues that result from not being able to manipulate UV coords in the vertex shader in some cases.
