Hi SupportTeam,

We port the DSI LCD Panel driver and it seem work to show ubuntu desktop.
But we run into flicker issues .
when click mouse right key at screen top edge position flicker happen,
Move to another position, flicker go away.

Could you run something that would render the screen and see if you could see this issue becomes worse?

For example, play a video file. Also, try full screen app and non-full screen one.

No Flicker Issues when play full screen h264 video .

I also observe screen flicker two-three times, before Ubuntu enter into standby mode.

Could you also try non-full screen case? Are you sure the panel supports the mode you programmed in dts?

Yes, I try to play non-full screen video in the website, still not see Flicker issues.
