Comment 8 for bug 421048

This bug also showed up recently on my Intrepid desktop install with nvidia-glx-180.

I would also like to note that if I mouse click on the dots they blink. This may be due to a screen redraw at the X layer. Moving a window over the dots will also make them blink. It seems that X firsts draws the correct content then a moment later the dots reappear, thereby causing the blinking.
