Find window

This sounds like a problem of missing invalidatation. BTextView calls FillRect() with the view color on Draw() when Autoresizing mode is enabled. What happens is that the view which then covers the BTextView/BTextControl doesn't get invalidated, and so it doesnt' cover the rect previously filled by the BTextView.

This is the same problem (I think) which happens when replicants are deleted, and the background isn't resttored till the are is triggered for invalidation. I had a look at ViewLayer::RemoveChild(ViewLayer* layer) and it seems we don't invalidate the parent view when a View is detached. Maybe we should.
