Hi I have a dell vostro 3550 laptop with hybrid graphics. An amd radeon hd 6600m and the integrated intel graphics.

I'm only using the integrated chip.

After a few days my Desktop started flickering, most of the time when I'm reading or editing text.

I noticed that xorg.log will get spammed with those messages over and over each time the display is flickering:
