GLSL Shader Optimizer Fail On Android Start

Hi, i am trying to launch a blank project on my android phone but the screen is entirely black and xenko outputs this error:

    Warning: Could not run GLSL optimizer:
        glsl_opt: (140,9): error: illegal use of reserved word `usamplerBuffer'
        glsl_opt: (140,9): error: syntax error, unexpected ERROR_TOK
    Warning: Could not run GLSL optimizer:

        glsl_opt: (140,9): error: syntax error, unexpected ERROR_TOK

What´s going on? I’ve tried reinstalling xenko and running it without my firewall enabled.

Hi,
Sorry to hear you’re having some issues.
Could you give us details about your Android device? (brand & model)

Thanks for the quick response! I have a Samsung Galaxy S4 i9506.
