Hello, i think i have also the same problem on my lg g6 +.
For example when i am watching a page or using an app, after some moments when i return back to home page, i see a bit the shadow of the app or previous page on the top of the background image.
I am really careful about saving battery. Can someone please help he on this issue. I appreciate it.
Thanks in advance.
