I've noticed this strange problem in windows11. Whenever the computer has to reboot for a windows update, the log in screen defaults back to that wavy default blue one. Now iF I go into settings, it shows the correct wallpaper as applied. Next reboot it will be back to normal. No other reboot or on/off cycle causes problems.
It's a really minor problem that fixes itself, but it's just odd.
