In general, Java Swing (the rendering technology behind Vision) does a poor job at transparency. This is a classic symptom - a 'dirty' region that is overpainted multiple times. If there's an 'opaque' property exposed on the component, changing its value _might_ help fix this (if you need transparency) but the simpler solution is just to not deal with transparency 😃
