      Imx8mm evk android hdmi shows some small white horizontal lines in a solid background. For example, you can open the clock application, then slide the mouse to see some small white lines.

      However, in Linux I repeatedly tested the above problems, I compared the mipi2hdmi driver, this part is consistent, the difference is that the display part of the android added the fence synchronization mechanism, I do not know whether this is caused by the difference Phenomenon, can you help me?
