Yes, I know, I'm a strange guy, but I'm feed up with transparency and want a non transparent desktop even with desktop effects enabled.
So I proceeded to disable transparency everywhere and started to look after a non transparent plasma theme (i.e., non transparent panels, non transparent widgets...) but found only one: Big Blue.
(BTW, it's a really nice theme)
So the question is: are there any other non transparent plasma themes? I can tolerate a transparent folder view background, but nothing else! not even a bit!
Thanks!

Isn't Aya mostly non-transparent? If you prefer the opaque style of a plasma theme (i.e. when desktop effects are disabled), you can always modify the theme to use the opaque style all the time. A short description can be found here: viewtopic.php?f=67&t=96664#p202971

Thanks, Hans. That was quick!
Notifications and tool tips from task bar and system tray are still transparent on aya...
I'll check the solution on the other thread. But if someone knows other themes like Big Blue, please post them.
Thanks again!

A few I've found and verified:
Leichtsinn - if you like white/light-gray
geek, or its light counterpart: geek-light - if you like plain flat (matches color scheme)
Others that look like they may be, but I haven't verified:
Vintage - KDE3 look-alike
win-classic old windows look-alike
