Ok this has just started since about 2 hours ago.
I found out sometimes when I'm using Firefox, my screen would "break" and produce images like below:
(when I scroll up or down, more would show up on the screen, or even flicker)
My current monitor is only about half a year old I think, and I have tried using other browsers including IE, opera, Chrome when the said issue occurred, they all display the screen properly.
(I constantly toggled between them and FF, in case the issue just happened to disappear when I switched browser)
I'm actually kinda clueless on how to fix this...any suggestion?
