Desktop effects messing with window title bars in KDE 4.2

Hello, I didn’t have this problem with 4.1 and it’s not that big of a deal it’s just annoying but with the desktop effect enabled, parts of my minimize, maximize,and close buttons will disappear untill they are “rolled over” with the mouse.The same is also true with the program symbols in the left corner of a window title bar. any ideas? Thanks
