Removing profile picture freaks out GNOME

When I installed the system, the profile picture was a default letter S (taken from the username). I changed it, didn’t like the result and removed it. Now the default picture is this garbled mess that looks as if my video drivers are failing.

I already tried:

  • Deleting ~/.config and ~/.local/share.
  • hardware.graphics.enable = true;
  • Rebooting.

Lmao.

This is from /var/lib/AccountsService/icons/synalice. The file is corrupted btw, I can’t attach it here without exporting it through Gimp first. Discourse doesn’t recognize it as PNG othervise. Here is the broken PNG file as an archive: https://files.catbox.moe/lpo61l.zip

I duct taped it by running sudo rm /var/lib/AccountsService/icons/$USER, but this doesn’t really fix the underlying issue. Adding and then removing the pfp again causes the glitched file to reappear.
