**System Information**

Debian 9 x64, nVidia GT620

**Blender Version**

Broken: 2.76 (from web)

Worked: 2.75a (from web)

**Short description of error**

This is a Filter 2D download from doesn't-know-where (I couldn't find source). It is a Blur filter with amount and multiplier values. It works pretty well in 2.75a. Since 2.76, it doesn't work anymore, the output is only a bit darker. No blur.

Shader code is:

/* Simple Box Blur * Higher amount = slower * multipler property does not affect performance */ uniform sampler2D bgl_RenderedTexture; uniform float bgl_RenderedTextureWidth; uniform float bgl_RenderedTextureHeight; uniform float amount; uniform float multiplier; vec2 pix = vec2(1.0 / bgl_RenderedTextureWidth, 1.0 / bgl_RenderedTextureHeight) * multiplier; void main() { vec4 sum = vec4(0); int i, j; for(i = -amount; i <= amount; i++){ for(j = -amount; j <= amount; j++){ sum += texture2D(bgl_RenderedTexture, gl_TexCoord[0].st + vec2(float(i), float(j)) * pix); }} gl_FragColor = sum / pow((amount + 1) * 2, 2); }
