Sample code 12_camera_vl2_cuda does not support e-CAM50 at full size

I build the sample code in the folder of /usr/src/jetson_multimedia_api/samples/12_camera_vl2_cuda/ and run the app at:

./camera_v4le_cuda -d /dev/video0 -s 2592x1944 -f UYVY -r 28 -c

The video on monitor is completely wrong (horizontal strip lines). Only the square on top left corner drew from CUDA is correct.

When change the command to:

./camera_v4le_cuda -d /dev/video0 -s 1920x1080 -f UYVY -r 65 -c

The video is properly displayed on screen.
What’s wrong with it? Is it a bug on the Jetson Nano sample code or it is something camera related?
