FWIW this was an issue with Gazeo 9 and this comment https://bugzilla.redhat.com/show_bug.cgi?id=1816487#c1 says: "A workaround is to override the session with environment variable XDG_SESSION_TYPE XDG_SESSION_TYPE=x11 gazebo" Whilst this comment: https://bugzilla.redhat.com/show_bug.cgi?id=1815270#c3 "It looks like it's an OGRE/Wayland issue. I found a similar error report from rviz here: https://github.com/ros-visualization/rviz/issues/1442 The work-around listed in the bug report works, and gazebo launches properly: QT_QPA_PLATFORM=xcb gazebo One way forward is to force gazebo to use xcb platform. I'll see if there's a way to do that in code so you don't have to use the environment variable." None of those made a difference.
