Description Antonio Rojas 2011-05-26 10:23:11 UTC 
Version:           unspecified (using Devel) 
OS:                Linux

Using KDE 4.7 beta 1.
Shadows of maximized windows are visible behind the panel. This doesn't look good, maximized windows shouldn't have shadows.

Reproducible: Always

Could you please provide a screenshot? My windows don't do that.

notice the red glow visible behind the panel
Comment 4 Martin Flöser 2011-05-27 18:54:15 UTC 
which window decoration are you using? Could you please provide a screenshot of the complete desktop, that would help to identify anything "strange".

I'm using oxygen (with ridiculously large shadows to make the bug more obvious)

@Martin
Should this be dealt with by Oxygen, or by KWin ? 
(I would have expected kwin, since oxygen would need to change its metrics etc. on maximize state in order not to do that) ... 

And if kwin ? Then should be re-assigned, I guess ...
Comment 8 Martin Flöser 2011-05-30 16:44:41 UTC 
I am not sure whether this can be handled in kwin correctly. Sure we can ignore the padding for maximized windows but it could look strange. I think it makes more sense to adjust the decorations to have 0 padding and adjusted rendering.
Comment 9 Hugo Pereira Da Costa 2011-05-30 16:50:18 UTC 
Martin, 
I actually was thinking that the easiest is just ... Keep padding, etc. unchanged, and well, not to paint the shadow when the client is maximized.
Makes sense ? 
If you agree, I'll push and close.
Comment 10 Martin Flöser 2011-05-30 17:16:47 UTC 
if possible try to adjust the padding calculations as having it just translucent means that we have 
to render more
