I observe a similar problem. I have Dell Latitude D620, and external display works fine until I try to disable internal screen. When I disable, I get small visual issues all over. I attach a couple of images. First image is a screenshot of konsole. It shows a text cursor (white block), but two characters later there's stay underscore. It randomly appears -- e.g. if I start typing first character somethings gets struck with underscore. Second screenshot is from kmail. Note that some items have bluish underline. This appears when I hover over items with the mouse. The item under mouse is highlighted in blue -- which is expected. But then when I move mouse, the buttom part of this highlight "sticks". It almost looks like there's off-by-something bug caused by absent first monitor.
