Version:           unspecified (using KDE 4.6.2) 
OS:                Linux

When 30 bit display color depth is enabled in xorg.conf (Depth 30 and DefaultDepth 30) krunner/panel and kickoff have a black rectangular background. The shadow isn't displayed too. It doesn't happen when desktop effects aren't enabled.

Reproducible: Always

Steps to Reproduce:
Enable 30 bit color depth.

it might be a problem related to Qt::WA_TranslucentBackground: the opacity of the terminal is ignored in konsole too.

Is this still valid for KDE 4.8.3 or trunk?

Hello! Plasma 4 was replaced by Plasma 5 four years ago by the KDE community. In that time we have made great strides in stability and functionality. We are closing all Plasma 4 bugs as most of them are no longer applicable to the new frameworks Plasma 5 is built upon. If you could, please re-test with the latest version of Plasma 5, and submit a new bug to "plasmashell" if you continue to have an issue. Thank you!
