Description ALeXeY 2013-07-27 18:20:53 UTC

The 4-th curve (alpha channel) in the color adjustment layer don't work as expected. It only affected the overall transparency of the layer, regardless of underlying brightness.

Reproducible: Always

More precisely, only the last point of 4-th curve affected the transparency.

I don't see any problems. It works as in Gimp. Can you show a screenshot of the issue?

Yes, it works. So, this is no bug, it's is my mistake. I'm sorry, just misunderstand how the alpha curve works.
Thank you!

No problem -- it's always good to check!
