Please provide complete information as applicable to your setup.

*• Hardware Platform: Jetson AGX Xavier
• DeepStream Version: 5.0
• JetPack Version (valid for Jetson only)
**• TensorRT Version: 7.1
• Issue Type: bug
• How to reproduce the issue ? (This is for bugs. Including which sample app is using, the configuration files content, the command line used and other details for reproducing)

I’m running yolo in deepstream on the Jetson AGX. In the resulting video with detection bounding boxes, the borders seem to flicker randomly. In particular, the edges will change rapidly from red to gray and back between frames, and they will do so seemingly at random. The video is 640x480 from a logitech webcam.

The following don’t seem to affect the problem:

  • Turning on/off nvtracker
  • Using yolov3 or yolov4 as the primary gie
  • Using mp4 video as input to the deepstream pipeline.

As a result I suspect the issue is with the nvdsosd, but I’m not 100% sure. The app has been configured to display red bounding boxes, so I have no idea where the gray lines would be coming from. Any ideas on what might be going wrong and how I can fix the problem?
