Bug Description

As mentioned, after a lock-wake cycle, the wallpaper turns to pixel garbage as seen on the screenshot.

Workaround: Setting the wallpaper from GNOME Tweaks, just not in the same adjustment mode as before. For example, if the adjustment was set to Zoom, now I must set it to something else to repair it. Setting it to Zoom again turns it once more into pixel garbage.

This sounds like it's going to be the same Nvidia backgrounds bug as 1809407. So let's wait till that is resolved before treating this separately.
