Visual artifacts found when using Intel media SDK VPP on few machines

Working with intel media sdk , succeeded with the following scenario.

Capturing the screen and encoding those images using hardware h264 codec. Could play the encoded h264 bitstream using ffplay. But when I used the same code on a different windows machine, found some difference in colors.

In order to find the problem, separated VPP and encoding blocks of code. And tried software implementation of Intel media SDK, the bitstream was fine. With hardware implementation of VPP, found artifacts.

Used intel media sdk tutorial  0.0.3 and attached the system analyzer report(Amith-PC-HW-report.txt) 

and the screenshot of the color differences(scaling-artifacts.png) and actual colors(scaling.png).

Any help resolving this would be appreciated.
