Screen grab of mission control with a blank desktop, showing the minimize button.

In the game Factorio, the following triggers the bug I'm describing:
- Start application
- Put application in full screen mode
- Perform updates. This will close the window and open a new one.

Result: The window that was closed leaves a blank (= black) desktop behind in macOS mission control. macOS behaves a bit strange when you try to activate this desktop. This was reported on their forum (https://forums.factorio.com/viewtopic.php?f=48&t=70191), but they replied that it's an SDL bug/problem.

Expected behaviour: the desktop should be removed the moment the window is closed.

Work around: When the application is closed, the empty desktop(s) disappear as well. Also it is possible to minimize the blank desktops from mission control, which will also cause them to cease to exist.

Note: Since I'm not the developer I don't know the version of SDL, but of course I expect it's the most recent stable release.
