imx6qp + dm5150 tvin green line

[WeiWeiBo]

Hi  excuse me

we have a board as below information 

board: I.MX6QP

OS: yocto 4.19.35

question: we have a tv-in chip dm5150 on this board, and when we use the mxc_v4l2_tvin.out tool to test video play, we see the screen green line as below photo occasionally, not always on screen, it seems cache issue, does anyone can provide an opinion?
