Blueprint components window doesn't work properly when r.ClearSceneMethod=0

We’ve recently set the following setting in our DefaultEngine.ini:


This is for the sake of performance, since there’s no need to clear anything when we’re using terrain and a sky sphere.

However, when this is set, this seems to affect more than the game – some editor windows don’t clear their backgrounds, including:

-The particle effects preview window
-The blueprint components window

Is this a bug in UE4, or should we be turning off scene-clearing some other way?

Hey Mothership.Entertainment,

I’m reporting this issue internally. Thanks for the report!
