UICapturedEffectImage does not work with 'ScreenSpace - Overlay' in edit mode

[Scarabay]

Hello. I can't make it work with this UI mode. On enable canvas (or any child) with UICapturedEffectImage attached to it, an error appears:
[d3d11] attempting to ReadPixels outside of RenderTexture bounds! Reading (0, 0, 290, 452) from (736, 414)

Unity version is 2018.2.2f1

Hi @Scarabay

Thank you for reporting the bug!
I will check it later.

Well... on edit mode only?
Maybe, (290, 452) is inspector view size, and (736, 414) is game view size, right?

To reproduce:

1. Open 'UIEffect_Demo.scene'.
2. Select 'Canvas/Transitoins/Transition - Capture Fast' in hierarchy.
3. Press 'Capture' button in inspector.
