screen flickering
Hi,
someone could help me with this weird issue?
Since yesterday, my macbook air is experiencing some strange screen flickering problem.
It appears repeatedly, while I'm working, a flickering on the left-bottom of the screen.
If I move the cursor to the corner to see the desktop then it disappears.
Does anyone has a clue of why this happens and how can I fix it?
Many thanks,
Anna
