Problem when two layermasks in one picture

Hello list

I just came across a problem, that I have never came across in gimp2.6.

When isolating a flower from the background, it works fine. Put another transparent layer on top, making a stroke with white paint. Add a layermask to this layer.
Now using a black brush on the layermask to make some of the white stroke transparent.

The flower underneath becomes transparent, and the white stroke doesn't becomes transperent on some places, the black brush doesn't seem to work on the layermask.

Is this a known bug?

Thanks for your help

Can't reproduce the problem on my own GIMP 2.8.0 - was I reading the steps correctly?

I tried: 1 - Open a convenient image, add layer mask (full opacity). 2 - Switch to the layer mask and paint away. (works as expected) 3 - Add a new layer (transparent) and paint some strokes 4 - Add a layer mask (full opacity) to the second layer. 5 - Switch to the layer mask and paint away. (still works as expected)

Remember that adding a new layer mask doesn't automatically switch to it for editing - you must do that yourself. From what you describe, it sounds like you're actually editing the first layer mask (the flower layer) instead of the second (the white stroke layer).

I'm not sure of how to proceed now, do I report this to Ubuntu-developer-list?

FWIW, this is unrelated to GIMP. Firefox+flash draws over itself; Konqueror/rekonq does the same; Chromium always renders within bounds but sometimes inverts the red/blue chroma. In general it's all a mess under (K)Ubuntu; I don't know about other distros.
