All of the editor windows are completely black on the Linux machine with the exception of the splash screen.
This occurs for the Unreal Project Browser, toast windows and game windows.
The functionality of the Project Browser window still works in terms of being able to close the window with the X button in the top right.
I do not see this issue on Windows.
