I could describe them as a noise but it is very noticeable when I read /dev/random file. Steps to reproduce: 1. Enable kde composer with vsycn enabled (any method will do). 2. Open some app which has black background. 3. Execute the following: dd if=/dev/random of=/dev/null bs=4096 count=1000000 oflag=sync Results: Random white horizontal stripes on the screen appear. Life time of every stripe is less 1s.
