Public bug reported: 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.
