You need to set the dynamic texture as pre-multiplied as well as enable the right blending mode.

This blending mode should be set to ALPHA\_PREMULTIPLIED\_PORTERDUFF but when doing this there’s a line in the shader code that is added: `color.rgb *= alpha`. However, we don’t want this to happen, we only want to set the OpenGL blending factors to 1 / ONE\_MINUS\_SRC\_ALPHA / 1 / ONE\_MINUS\_SRC\_ALPHA.

The easiest way is to override the blending factors and set the ones we want in the `material.onBind` observable:
