Sorry if it is duplicate, I tried searching the bug report, but can't find anything matching.
With the latest updates to Debian Testing, the GNOME UI is scaled to 1.5 from the previous default of 1. The screen now shows forcefully zoomed and breaks games and other full-screen apps.
For the GNOME Shell (the one after we login), I changed the scale to 100% in GNOME Control Center -> Displays -> Scale. Now the shell is back to normal.
But the login screen (I think called GDM) is still on 1.5 scale. How can I revert this or is it a bug that will be fixed?
