Hi @arunava_nag, we experienced the same ros2/rviz error that you describe. In our case the problem was not with Qt, but with loading the default config using yaml-cpp. This results in the empty window. Can you check if you have a yaml-cpp 0.5 package installed with apt? If yes, uninstall it and try again, ROS2 comes with its own yaml-cpp. Are you using the binary build of ros2/rviz or are you building it from source? --- [Visit Topic](https://discourse.ros.org/t/rviz2-qt-problem-creating-accessible-interface/3416/3) or reply to this email to respond.
