[Intel][sMedio] Flicker issue under clone mode in Windows 10

[RWang15]

Recently we hit a strange issue in the laptop of OEM customer with Intel 9th Gen CPU/GPU, it is ok in other Intel Graphic cards, and other IHV Graphic Cards.

When switching to Clone mode, the video presented in sMedio UWP DVD player will flicker.

1. When disabling MPO, this issue will have gone.

2. When there are some system UI above the player, for example, Taskbar, start-menu, this issue will have gone 3. When our OSD is enabled, this issue will also have gone.

Now OEM customer pushed sMedio to fix it as soon as possible, but we think it is related with graphic driver, especially HW MPO introduced from Intel 9th GPU, can you give some hints for us?

If MPO is disabled, Windows DWM will handle composition, if MPO is enabled, Windows DWM pass through UI and player to Intel Graphic driver side, and Intel Graphic driver will handle composition.That’s why I think this issue is caused by Intel Graphic driver.

Thanks.
