Strange rectangle on ubuntu 18.04

[gabrielmcsousa]

Whenever I run RoboViz and the RCSSSERVER3D on Ubuntu 18.04 I get a strange rectangle in the middle of the field. It does not seem to cause much of a problem and it goes away as soon as I run any team or agent, but since i have never seen this prior to switching from 16.04 i wonder if it is 18.04 related. Has anyone seen this before?

I've seen it occasionally with Ubuntu 16.04, but much more frequently with 18.04. If you type 'U' to get a full state update from the server it usually fixes itself.

For me, this seems to occur if the server starts while RoboViz is already running. As far as I can see, the reason for this are wrong/missing values for the field length and field width supplied by the server.

I think there is also a "FieldLength variable missing" warning in the rcsserver3d console when it is launched. Maybe there is some relation to this rectangle.

Yes, pressing "U" to refresh does fix the problem too.

I just realized, when testing the refresh idea, that the outer and goal lines are gone when the rectangle is there, so indeed it might be related to those variables.

Closing this since it's a server issue.
