White background on resume from suspension or from screen turned off

### What Happened?

After resuming from suspend, or when waking up the screen after it turned off, 8/10 times the greeter background color/image does not load properly and instead the whole background is, searingly, white, therefore making very bad contrast with certain elements of the UI, like the clock.

When I've tried to forcefully suspend/turn off the screen the issue has not happened.

This only happens on my desktop, not on my laptop, both running latest elementary OS

### Steps to Reproduce

1. Wait for session to lock
2. Wait for screen to turn off
3. (Optional) Wait for the computer to suspend
4. Wake up the computer

### Expected Behavior

The background should be consistent every time when logging in.

### OS Version

6.x (Odin)

### Software Version

Latest release (I have run all updates)

### Log Output

```shell
Logs will be taken the next time it happens and added here.
