Fonts and texts (including Gnome UI) are gone after coming back from Standby (nvidia + Wayland)

Steps to reproduce:

1. Perform a clean Ubuntu 21.10 install with nvidia drivers.
2. Log into Gnome with Wayland.
3. Let the PC go into standby.
4. Wake it up again.
5. All fonts, texts, icons are almost completely gone, including the unlock password dialog and the Gnome UI after unlocking.

(New windows seem to be OK.)
