Decreasing windows titlebar tansparency, where?

[jazz.h]

It seems I can't find anywhere a setting for decreasing windows titlebar transparency/opacity.
I'm currently using FormaN decoration, but it's more-less the same with all of the decorations...

Haven't played enough with theme settings.
But did you look in Settings>Workspace Appearance>Desktop Theme>Details ?
Just guessing here.

No, it's not there.
It seems that this setting is not configurable, if you want untransparent window title bar, you have to pick such window decoration...

I'm not sure this will be helpful or not. I have wondered the same thing. How do I change one little bit of a particular theme. I looked thru my directory structure one day and found config type files related to themes. These files had lines similar to Conky: argb value = ___ or opacity =____ or color = ____. That sort of thing. I haven't tried changing any of these entries, can't remember where the heck I found the files. I'm just guessing that you need a desktop that supports transparency, like KDE/Kwin and you need to find these files to change the values, if they are even available.
