Version: (using KDE 4.2.0) Installed from: Ubuntu Packages I thought that there was a bug filed for this already, but I cannot find it. Currently the user cannot configure no transparency for the Plasma panels when Composting is enabled. This makes some parts of the screen difficult to see. See attached screenshot. The fix would be allowing the user to configure no transparency on a per panel basis.
Ah, found it! Sorry for the noise! *** This bug has been marked as a duplicate of bug 165795 ***
