Gazebo Sim Blank Screen

[brettbeyer99]

My program launches perfectly fine, and the colcon build is successful. However, when Gazebo Sim launches, I get a blank screen. When I scroll I can see a silhouette of the drone appear, however, when resting the Sim is simply a blank.

RViz works perfectly, and I can see the drone fly arround using the key-controls, but again, Gazebo Sim does not seem to be working appropriately.

Has anyone come across this issue or have any suggestions?

Also, does anyone know if this simulation would work in Gazebo11 or Gazebo9 instead of Gazebo Sim?
