SMAAPass fragment shader does gamma correction. Is it correct?

[dllb]

The renderer (with antialias = true) does a good job on outlines, but nothing else.
It won’t antialias any texture detail, at all.

But, level-1 of SSAA is still light and antialiases everything.

Indeed. That’s because setting antialias to true enables (4x) MSAA which only handles geometric aliasing.

Yeah, like so:

(antialias = true)

Level-1 SSAA seems similar, if not a bit better:

Then I tried setting premultipliedAlpha: false when creating the renderer and got this image with the default smaa shader:

You have changed the angle, so it reveals more artifacts.
Try to find the worst case and freeze it like I did above, to be able to make A / B comparisons.
