Comment 2 for bug 652863

same here with Maverick RC: I upgraded to maverick yesterday. The bug does not appear when i'm using kubuntus livecd. Also transparence was working yesterday, so I guess an upgrade is to blame for it

y graphics card according to lspci:
02:00.0 VGA compatible controller: ATI Technologies Inc RV770 [Radeon HD 4850]

I tried with the open source driver and fglrx: transparent plasma panel + decorations are not working with either of them
