This bug was reported to the UPBGE repository but it seems to come from blender sources after a reproduction of the bug in blender.
https://github.com/UPBGE/blender/issues/433
Copied bug description:

If you are in world tab in the properties panel and switch to the lamp tab, the preview panel is showing the world preview instead of the lamp preview (see pictures).
This happens to all types of lamps.

The bug occurs when:

  You were in world settings and moved to lamp settings
  You can move to another tab and back, the problem doesn't get solved

The preview gets back to normal when:

  The lamp values are changed
  The upbge window gets moved
  The upbge window gets resized (width, height doesn't change anything until the height is around the half of the screen size)
  The properties panel gets resized (same as above, mostly width and so on...)
  You switch to texture tab and then back to lamp settings

Closing the properties panel (e.g. by changing it to 3D view) and reopening it doesn't help.

So I think this is because of missing UI redrawing. I have no clue on how Blender code works but this might be causing it.

File (same as default open file) : preview.blend

Yep, after moving from World to Lamp, keeps World preview until you make a minor change in settings.
Suspect refresh upon focus is not the same as refresh upon setting change.
