In Response to Clonk-Karl

So the error message is

ERROR: 0:74: '=' : cannot convert from '3-component vector of float' to '2-component vector of float'

I think it relates to this line:

vec2 lightCoord = lightTransform * vec3(gl_FragCoord.xy, 1.0);

But it is not clear to me why it does not work. My Intel driver works with it. Can you try to replace this line by

vec2 lightCoord = (lightTransform * vec3(gl_FragCoord.xy, 1.0)).xy;

in Graphics.ocg/ObjectLightShader.glsl? Also, you'll have to replace

float ambient = texture2D(ambientTex, ambientTransform * vec3(gl_FragCoord.xy, 1.0)).r * ambientBrightness;

by

float ambient = texture2D(ambientTex, (ambientTransform * vec3(gl_FragCoord.xy, 1.0)).xy).r * ambientBrightness;

in Graphics.ocg/AmbientShader.glsl.
