Nimbus L&F: Slider thumb in pressed state shows up a white pixel at the bottom.
This is observed on Nimbus L&F on all OSes, with the current 6u4b02 pit build.
Steps to reproduce:
1)Run SwingSet2 Demo with the nimbus L&f and tab to the Slider demo.
2)Press the Slider thumb.
Observe that a tiny white pixel appears at the bottom of the slider thumb giving an impression that the thumb is cut at the bottom.
Screen Shot with a magnified image is attached fo reference.
