RVIZ crashes on load with segmentation fault (core dumped)

[lschirmbrand]

Hey. I'm trying to run a SLAM Robot including rplidar_ros and hector_slam as a ROS project inside a docker container. The installation should be correct and for example the launch of the lidar is working (launched as roslaunch rplidar_ros rplidar_a3.launch).
That makes me think, that the docker is set up correctly. However, when I try to launch a node which uses rviz, rviz is crashing. Sometimes rviz pops up and crashes like half a second later, sometimes it doesen't even show up.

So if I launch the file like this: roslaunch rplidar_ros view_rplidar_a3.launch the error looks like that:

log file: /root/.ros/log/44a83bc6-7521-11ec-89d0-0242ac110002/rviz-2*.log

So first I thought it's an issue with the qt and xserver, but other graphical applications work. I did a lot of research to find the issue and saw a recommendation to run rviz normally. So the next thing I did was run rviz like this: rosrun rviz rviz.

This proceeds in the following error:

Help would be wonderfull.

rviz in docker works w/o problems for me. I guess you followed the general instructions here?
