step-wise noise on MP4 Media Engine on Elkhart Lake

[RySAP]

When I played MP4 video by Microsoft Media Foundation sample program on Celeron J6412, step-wise error like following picture appears in the bottom left corner. 

It only appears on Elkhart Lake and Media Foundation.

I attached microsoft's Media Foundation sample code.   You can see this MP4 decode noise by this code.

Only Elkhart Lake shows this noise.

Tested platform 

- Tiger Lake Celeron 6305E

- Elkhart Lake J6412

- Braswell  Pentium N3700

There is some frame missing on Braswell, but step-wise error is not seen. 

Tested Video

- 1920 x 1080 30p

- 1920 x 1080 60p

Frequency of occurrence changed by resolution, but same error appeared.

When I played them by Media Player, no noise appears, no error appeared.  

When I played programs written by Direct X, no error appeared.  

Could you give me any advice?
