Hello, I have some constant data published as MarkerArray topics so it can be seen in rviz.

Instead of streaming constant data, I thought it would be much more optimal to use latched topics to publish the data once and sending it when it is needed.

However, it does not work that well: in rviz, the first time the marker is rendered it is ok, but if the rendering stops for some reason (i.e. I restart the demo and some tf frames are temporarily not available for instance), it is not displayed anymore.

Is this a bug? What would be the best strategy in order to keep a consistent display?

Thanks!

I have the same problem. Sometimes everything displays fine, sometimes not.
