I've got exactly the same translucency problem after upgrading to kdelibs4 (3.2.3-2).
I already had the problem on my laptop, with ati drivers. So, just to be sure, I tried to upgrade my home pc (with nvidia drivers), and the problem occured at the same moment. I did a full upgrade, and then, as I was using the plastik style, I had to install the kdeartwork-style, and this one automatically upgrade kdelibs4. Is there any way to rollback to the previous situation, or, better solution, to fix the problem? Thanks in advance, David -- David Mathy Email: [EMAIL PROTECTED]
