color distortion with rockchip mpp vp8 hw decoder

I am using mpp library to decode vp8 data, color distortion starts happening around the static part in the frame and then spread through the whole frame.

H264 part works perfect.
Is there anyone who has seen this kind of behaviour with VP8? Is there any specific setting needs to be done for VP8 in mpp?

I am using RK3399 friendly elec board with Ubuntu image downloaded from friendlyelec website.

This issue seems to be related to RK3399 board only.

If i run my application on another(RK3288) board, there hardware decoding is normal(ie. no color distortion).
But if i run it on NanoPC T4 then color distortion happens.
I have tried two images from FriendlyElec download section: ie.
1. rk3399-eflasher-friendlydesktop-bionic-4.4-arm64-20180921.img
2. rk3399-sd-friendlydesktop-bionic-4.4-arm64-20190926.img

if anyone want to give a try on their RK3399 board, i can share the application and webm file as well.
I seek help from FriendlyElec community, if you can confirm whether it is an kernel space issue or hardware issue.
