Rviz point cloud alpha flickering #1287

Open dan11003 opened 5 days ago

dan11003 commented 5 days ago

Hi, I recently migrated my code base to ros2 and is experience “flickering” for point clouds in Rviz2. It happens when using the alpha in PointCloud2 to improve visualization clarity. Occasionally, the effect of reduced alpha (increased transparency) vanishes, resulting in sudden very intense point clouds. I.e. point cloud is still visualized but the alpha seems to flicker. The decay time is set to 0.

Not sure if this relates to any other open Issue or not.
