The reported problem is during login, not after successful login. I don't think mutter configuration has any effect before graphical login.
Ubuntu's cursor theme may come from 'yaru-theme-icon', but does gdm's? Two files affect the observed condition: /usr/share/icons/Adwaita/cursors/left_ptr /usr/share/icons/Adwaita/cursors/xterm These come from the package 'adwaita-theme-icon-full'. If the package is not installed I have no login screen mouse pointer. Install the package and the pointer appears. Leave the package installed and deleted the two above files and the pointer is gone. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1972080 Title: [mgag200] Mouse cursor is a semi-opaque white square To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1972080/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
