I have some trouble with my DELL laptop. It is an old laptop, but the problem has been occuring since 2012. Recently my new computer broke down, thus I am back on my old DELL again.
The problem is whenever I start usin more then one program, suddendly the whole screen is becomming blurry in a way (see attached picture). If I either scroll up or down, the blurryness disappears for a while but returns in maybe 10 - 15 seconds later. I have this problem with almost every program I am usin and it is really annoying.
I have no idea what is causing this, if it is a hardware problem or a software problem. Can it be some drivers that are not working properly?
Thanks i advance for any responses
