Hello,
since KDE 4.5 (at least) (opensuse 12.1) at the bottom edge of of the 'Task bar' (panel with kickoff, clock, pager, tasks, systray etc) there is a Blue Glow that appears when I get near it.

I've changed the desktop theme, window decoration and the widget style.
I've changed Every color in the Application Appearance > colors section so there is No blue.
I've changed the ~/.kde4/share/apps/desktoptheme/WhatEverTheme/ glow.svgz and task.svgz files so there is No 'glow' or a different color

But.... the glow remains. From KDE 4.5, .6, .... now 4.11.3-x

Why???
Where is it defined?
How do I get rid of it..

I run my desktop with the taskbar on the Top edge, Hidden and the 'Glow' is big enough that if a window, eg, Yast2 opens snapped to the top of display (monitor) it is sometimes next to impossible to grab the windows title bar because the glow interferes just enough. Fortunately I have option to be able to 'grab windows from any empty space' enabled.

Any ideas? I've been trying to solve this issue of mine for 2, 3 maybe 4 years now...

Additionally, is there Anywhere I can find a 'howto' or tutorial or developer manual on how to build my own theme? I would think there has to be a 'manual' or wiki that spells out All the files it takes and what does what in building a theme. There are a lot of parts and just as many *.svgz files. Which one does what and .... Anyone know?
I finally have a grasp on 'window decoration' is different files than 'window theme' and different than style > widget style and 'icons' are different than the 'system tray' icons from 'desktop theme' which I think are also the icons used in toolbars like konqueror...

Hope this is clear enough to get a handle on what I'm asking for..

If you are modifying the Plasma theme, it will be necessary for you to logout and back in again for the changes to be picked up. I would also suggest removing /var/tmp/kdecache-$USER/ after logging out to ensure no cached version will be used.

In terms of what provides the panel glow - I believe KWin provides that.
