Display frames are getting repeated when same output is connected to display as well as another m2m path. For example, In multi-camera example, when VISS output is connected to DSS as well as DSS M2M path, after few minutes of running, display and image descriptors frames are getting repeated for the display node.
This is one important data flow for customers, where the output could be displayed directly and also scaled down/converted to different format, before further processing.

It look like since DSS M2M returns the descriptors immediately after processing, whereas display node does not return the same descriptor immediately, it seem to be creating issue in the framework.
