The fullGeometry and the actualGeometry of the WorkspacesDisplay are set from the allocation of the overviews ControlsManager and the WorkspacesDisplay, that means they're only valid after those actors got their allocations during Clutters allocation cycle. Since WorkspacesDisplay._updateWorkspacesViews() is already called while showing/mapping the WorkspacesDisplay, that allocation cycle didn't happen yet and we end up either setting the geometries of the views to null (in case of the fullGeometry) or to something wrong (a 0-sized allocation in case of the actualGeometry). So avoid setting invalid geometries on the views by initializing both the fullGeometry and the actualGeometry to null, and then only updating the geometries of the views after they're set to a correct value. Note that this means we won't correctly animate the overview the first time we open it since the animation depends on the geometries being set, but is being started from show(), which means no allocations have happened yet. In practice this introduces no regression though since before this change we simply used incorrect geometries (see the 0-sized allocation mentioned above) on the initial opening and the animation didn't work either. https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1119 |

GNOME Shell
GNOME Shell provides core user interface functions for the GNOME 3 desktop, like switching to windows and launching applications. GNOME Shell takes advantage of the capabilities of modern graphics hardware and introduces innovative user interface concepts to provide a visually attractive and easy to use experience.
