This is very useful information indeed. In 0.9.8 an interface was added to check if your laptop is in a docking station and polls the docking status regularly. This somehow seems to trigger the blinking screen. Richard, it seems "polling" the number of active DRM devices causes the screen to blink. The complete bug report is at [1]. Any ideas how to addess this?
