Display rviz2 crash

Hi,
I am using the Ubuntu20 system with ROS2 and zed2i camera. Trying to run rviz for person detection, it ran well for a couple of times but then it started crashing.

[rviz2-1] 1650905914.139708040 [rviz2] [ERROR] InternalErrorException: Vertex Buffer: Out of memory in GLHardwareVertexBuffer::lock at /tmp/binarydeb/ros-foxy-rviz-ogre-vendor-8.2.6/obj-x86_64-linux-gnu/ogre-v1.12.1-prefix/src/ogre-v1.12.1/RenderSystems/GL/src/OgreGLHardwareVertexBuffer.cpp (line 125)

Thanks in advance.

@Flash this is a ROS2 issue, not directly related to the ZED software. You can surely find a solution by asking on https://answers.ros.org/questions/
