Hi,

Today I noticed a problem with alpha window in my application:

[1] http://s10.postimage.org/8mgva646h/2012_11_24_224749.png
[2] http://s11.postimage.org/ggnwedhkj/2012_11_24_230100.png

The edj file holds some images and Elementary objects. I'm sure some
before one or two weeks the application was running well.

You see in front of black background (terminal) the car looks well. But
on the white background it doesn't. But this car image doesn't have any
alpha information at this position. I don't understand it.

If I disable elementary alpha support it works better, but even not
all. And I like to have some elements transparent.

I'm using composite with opengl, but same problem with sw rendering.

To explain the problems in detail:

[1] This window had a solid background before.
See here how it should look like:
http://sourceforge.net/projects/openinfo/screenshots/openinfotainment.jpg
(minus the map. This are is transparent for this reason.)

See here the edc code:
https://gitorious.org/openinfotainment/oiui/blobs/master/data/sm/edc/MenuMainView.edc

"Rectangle01" is covering the background and should be black. But it's
not visible if the edj is displayed with Elementary alpha support.

The second image[2] shows even the same problem. Over black background
it looks good. The bars have no alpha information, but are transparent.
I don't understand it.
https://gitorious.org/openinfotainment/oiui/blobs/master/data/sm/edc/NavMainView.edc

And the white gradient rectangle is a white border image zoomed up:
https://gitorious.org/openinfotainment/oiui/blobs/master/data/sm/edc/NavInfoView.edc

The strange thing is that if I call the groups from edje_player that it
looks as it should. So it's no edje bug for sure!

Look here my Elementary window setup code:
http://code.google.com/p/stateval/source/browse/trunk/stateval/src/plugins/viewmanager/edje/GUIThread.cpp

As I've not modified my application at this point I wonder if maybe
some behaviour in Elementary changed or if this may be a bug.

regards
