Default Black screen when running (fixed) - 11-14-2019, 10:09 AM

OVERVIEW
In the scene editor of any working scene, when adding the model TrashPile(LARGE), TrashPile(MEDIUM) or TrashPile(SMALL) the camera view or object tree briefly flashes red and the object appears to be added successfully. When Run, an "Alice has encountered a graphics problem" error is produced along with a prompt to report the error. This is sometimes followed by a multiple exceptions error window. The run window itself is rendered either black or flashing black and blue, and the scene editor is rendered as a black screen. Restarting Alice 3 does not restore the scene editor.

SOLUTION
Delete the TrashPile object from the scene completely and save the project (alternatively, restore a saved file from before the TrashPilewas added). Restart Alice 3 and reload the project. NOTE: there may be additional objects which cause this graphics problem. I did not test them all.
