Version: 4.1.85 (using Devel) OS: Linux Installed from: Compiled sources I am running KDE 4.2 Beta2 from Kubuntu PPA. I am not sure of the steps to reproduce this because I come across it only once in a while. It usually happens when coming back from standby. From the before screenshot, you can see that the background color on the icons is white. In order to fix it, I click on the system tray border and the background turns black. The after screenshot shows what it looks like after the background turns black again.
Created attachment 29810 [details] The system tray when the background is messed up. Here is what it looks like when its messed up.
