I experience the same issue. After suspend the lock screen and background image is gone, leaving only a "white noise" (see attached image). From what I can tell, this bug is purely aesthetical, and has no practical implications. I can still log in and use my computer like nothing happened.

I am far from any expert, but the description of [bug #1809407](https://bugs.launchpad.net/bugs/1809407) does not sound entirely similar to what I experience and what OP describes, and the bug might not be a duplicate.
