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

[rhi]

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.)

[rhi (rfc2822)]

Hardware: NVIDIA GeForce RTX 2070, two screens

Attached: screenshots of screen corruption (photo of unlock screen, screenshot of Gnome UI after unlocking)

[rhi (rfc2822)]

Additional info: If you log out from the Gnome session (you have to know by heart where to click because there is no text) and log in again, everything works again. So it's some kind of temporary screen corruption.
