A crash will occur when editing the Draw Size of a Widget Blueprint in an Actor Blueprint class. Sometimes it will crash instantly after editing the Draw Size and other times it will take a couple of tries to trigger the crash.
RESULTS: The Editor will crash when the Draw Size values are adjusted.
Note: Typically crashes if values become negative or very high (8-16k+) as they surpass the limits of render resource creation.
