Short description of error
Viewport and outliner miss a drawing refresh after deleting objects from the outliner.
Exact steps for others to reproduce the error
- In the outliner, mouse over the light object, RMB > Delete.
Both viewport and outliner still show the lamp there, until something else triggers the update (e.g. resize editors).
Note if you mouse hover another outliner before a draw update you will get a crash.
