Description animtim 2014-02-10 21:37:57 UTC

Using disable alpha channel on a group layer is broken.
It worked before, I used it on some of my comics files.



Reproducible: Always

Steps to Reproduce:
1.On a new file, create a first "main" group layer.
2.In it, create first layer with solid shapes (in my case, it's a vector layer with some rectangles to make comics panels).
3.Then above the vector layer create a second group, with several new paint layers, and paint on each of these, taking care to draw on the same area as the solid shapes/comics panel.
4.select this second group layer, and with the channels docker disable alpha channel of the group.
Actual Results:  
the group image result becomes completly transparent

Expected Results:  
the group image result should be visible on the solid shapes/comics panel area.

More infos:

The problem actually is that it seems that now the "channels" docker enable/dicable alpha globally on all layers, and not on selected layer as it was before.

I'm not sure if that was actually intended change or a bug, but if it's not a bug, then I propose to add another column to enable/disable channels on selected layer as before.

Also we can add the disable alpha shortcut on group layers and all other layer-types (maybe just not on masks) in the Layers docker.

As a dirty workaround, for now I can open the .kra file with ark, edit the maindoc.xml and set channelflags="1110" on the layers I want, it works then perfectly.

SORRY, I forgot layer channels are accessible in the layer properties window, so that's not so_bad as I thought.. 

So I'd just suggest to add another column in the channels docker to access these if possible. But that's not so much important if it's already available somewhere else.

Is this still relevant?
