Hi, the author of “GDM Settings” app here. This problem is caused by GDM Settings. Sorry!

GDM Settings extracts and saves the unaltered default shell theme as default-pure. If the user was not using a custom shell theme before using GDM Settings, in order to not mess up the shell theme for the current session when modifying the system wide shell theme (which the app needs to do in order to customize the appearance of login screen), the app changes the shell theme of current session to default-pure.

Since default-pure is an exact copy of the default shell theme (with no modifications whatsoever), there should, theoretically, be no issues. Unfortunately, default-pure does not get upgraded to the latest shell theme installed on the system until the user applies settings through GDM Settings app again. This is what is causing the issue on your system. The shell has been updated to 44 but default-pure is still on 43.

To mitigate the issue,

  • Re-apply settings in the GDM Settings app.
    (This will update default-pure to 44)

or

  • Switch to another shell theme.
