I have ubuntu 14.04 installed in my system. Whenever I open the browser or an application and try to hover the mouse over any links, I get a black strip. For example, when I bring my mouse on any of the links, I will not see the description of the link, I get a black stripe. I use eclipse extensively, and when I get any error I don't see any help that usually is seen by hovering the mouse over the error line, instead I see the black line. I also cannot capture this weird movement in the screenshot. I cannot open GNOME color manager also to make any changes.
Can anyone help me here? It is really very important for me and I am not getting any links from Google on this. Any help from Ubunut gurus will make my project go smoothly.
Thanks in advance
