4. Go to the menu bar "Edit>Project Settings..." and go to the "Player" section then expand "Other Settings"
5. Disable "Auto Graphics API for Linux"
6. Switch the graphics APIs in the "Graphics APIs for Linux" list
7. Restart the Editor when prompted and observe the arrangement of the graphics APIs in the list

Expected result: the graphics APIs remain arranged in the order set right before being prompted to restart
