Major memory leak/bug in 4.12 editor.
I have tracked a memory with the new editor. I found that the “UBlueprintThumbnailRenderer::Draw” is spawning countless SpawnPreviewActor without deleting them every tick when a blueprint asset is visible in the content browser.
I wanted to give a heads up here as it is causing some crashing on my project. After debugging it more, i’ll post it in answerhub.

Not positive, but this sounds a lot like the I submitted recently:
Wasn’t caused by the Planar Reflections, something in the editor itself.
