Run SwingSet2 on Vista-Home Premium. Choose windows look and feel. Choose some of the demos such as FileChooser, ComboBox, List, etc. Notice the text rendered within the combobox, button, etc. You will see that some characters are antialiased predominantly in red color and looks odd. You can very well notice in the combobox demo - Look at the word 'Philip'.

I reproduced this on Windows Vista Home Premium on ATI Radeon X1600 PCIE. The video card is installed with the latest driver (7.8) and AERO is enabled on it. Also the system where I reproduced this issue is having a LCD monitor. This was not reproducible on 6u3, 6u4 with D3D turned off, 6u3 with ddraw turned on.

I have attached a few screenshots. Magnify them and look at the areas bound by red colored rectangles.
I noticed green colored test with RTF documents loaded onto the EditorPane, on the same machine. I have attached the screenshot of the same and the demo that reproduces it.
