Hi,

I see white lines on display whenever i do screengrab. Also, its visible sometimes when I do video encoding of frames coming from camera.

Is this known issue with imx8qxp(android 9.2.3)

Thanks in Advance,

Wasim

Hi Wasim

rev.C0 improved many features as described in

i.MX 8X C0 Migration Guide Migrating from i.MX 8X B0 to i.MX 8X C0

Please try that revision with Android supporting that part, like Android P9.0.0_2.3.2

Android P9.0.0_2.3.2 Documentation

Hi igorpadykov‌,

Thanks for your reply.

I can see there are lot of fixes, viz:

• GPU: Fix OpenCV and Vulkan conformance issues.

• VPU: Enhancement for encoder and decoder using different reset signal

• MIPI_DSI: Bug fixes to resolve MIPI DSI CRC issue for LP DCS long write.

But, I am using Rev.B0 and I don't think we can change it as of now.

But is there any chance of getting any fix for the issue I had mentioned above or is the issue fixable in B0?

Thanks

Hi Wasim

rev.B0 is not recommended for production purposes.
