Crash when moving ScreenCapture2DComponent with Forward Shading and No Shadows

Build Type: Binary build

Build version: 4.14.0-3195953

Description: I have a project with an actor that has a ScreenCapture2DComponent attached. If Forward Shading is enabled and Shadows are turned off (low quality), once the actor is moved it crashes the game/editor.

Repro Steps:

  1. Make a new project
  2. Enable Forward Shading
  3. Select Low quality for Shadows in the Engine Scalability Settings
  4. Now in the level create a new actor
  5. Attach a ScreenCapture2DComponent to the actor
  6. Assign a Render Target texture to the ScreenCapture2DComponent
  7. Run the game in the Selected Viewport
  8. Select the actor in the World Outliner and move him
  9. Expect a crash

For me this reliably reproduces the bug all the time.

Attached a log from the crash.
