7' Touchscreen V4 flickering issue with M3 on Android 5.1

I have been using this display along with M3 and run android on it, since the Version 4 of the screen hardware came with a 40 PIN connector along side the 20PIN and Parallel RGB, the screen started flickering even on the build provided by BPI themselves. The operations are OK, touch sensitivity is same, but the color looks sham, and screen continues to flick.

Are there any driver changes needed to resolve this ? please provide details if any.
