3 weeks ago Thank you for your feedback. The messages indicate that rviz2 cannot display point clouds fast enough due to rviz or ros performance bottlenecks. This can have several reasons, most likely related to the system (hardware, OS or ROS2). Use top, ps to check memory and cpu usage. Monitoring tools provided by the operating system can identify resource bottlenecks.
