Thanks for the bug report. The first thing to check is to please uninstall these extensions:
'native-window-placem...@gnome-shell-extensions.gcampax.github.com', '[email protected]', '[email protected]' We find so many gnome-shell bugs are caused by extensions that they should be removed as a first step. Then if the problem persists then please report it to the gnome-shell developers at: https://gitlab.gnome.org/GNOME/gnome-shell/issues and then tell us the new bug ID. ** Changed in: gnome-shell (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1866851 Title: lock screen scaled down backgound image in top left corner Status in gnome-shell package in Ubuntu: Incomplete Bug description: The new lock screen in gnome 3.36 looks strange, as if the blurred background image is being scaled down to the top left corner of the screen. background image being used is 1920x1440 pixel jpeg, display size is 3840x2160, with fractional scaling enabled and set to 175% on wayland.
