Hi Swarnendu,

I had the same problem with my Acer Aspire V7-331G with Nvidia Geforce
GT 630M card. Yesterday I figured out that my phantom display I've had
since 13.10 (both Unity and Gnome) is on and causes the graphics to
leave trailing artefacts and slight flickering.

I use my built-in display as primary and a external 19" Samsung as
secondary. The third display (probably my SVGA with no monitor
connected) was enabled but I disabled it and I no longer experienced the
flickering and trailing artefacts. This wasn't a problem in 14.04.

Head over to Activities > Displays and disable the third monitor if you
have one.

You might have a slightly different problem, but hopefully this will
work if you have the same problem as I did.
