When using Wayland, I expect the application to display a window with controls and sky display. Instead a blank window with a black background is displayed. There are no controls or sky displayed. Running under x-org works as expected.

Graphics:
OpenGL version string: 4.6.0 NVIDIA 510.60.02

Running from a terminal gives this text:

Warning: Ignoring XDG_SESSION_TYPE=wayland on Gnome. Use QT_QPA_PLATFORM=wayland to run on Wayland anyway.
