I have installed Ubuntu 14.04.2 LTS and I am new to Ubuntu, I have seen issues in different applications. The issue is where ever I move my mouse pointer it erases the text, it is not permanenet issue but it happens at random interval.
Please have a look at screenrecording: Video
Please have a look at below images and look the weird special characters it displays on the screen:
I am not sure it is hardware problem or Ubuntu problem. I did research but I could not figure it out as I am new to Ubuntu.
Is there any way to fix this or I have to re install Ubuntu all again.
