Subject: [PATCH 1/2] workspacesView: Avoid setting invalid geometries on views
|
|
|
|
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.

Subject: [PATCH 2/2] workspacesView: Only animate on show() when geometries
|
|
are already set
|
|
|
|
Animating the window clones of the overview requires the fullGeometry
|
|
and the actualGeometry to be set, which they won't be when showing the
|
|
overview for the first time. So don't even try to animate the window
|
|
clones in that case because the geometries will still be null and
|
|
accessing them in workspace.js will throw errors.
|
|
|
|
The workspace views will still get the correct layout as soon as the
|
|
allocations happen because syncing the geometries will trigger updating
|
|
the window positions. Since animations are disabled for position changes
|
|
when syncing the geometry though, we won't get an animation and the
|
|
clones will jump into place. That's not a regression though since before
|
|
this change we also didn't animate in that case because the geometries
|
|
used were simply wrong (the actualGeometry was 0-sized as explained in
|
|
the last commit).
|
|
|
|
If we wanted to fix the initial animation of the overview, we'd have to
|
|
always enable animations of the window clones when syncing geometries,
|
|
but that would break the animation of the workspace when hovering the
|
|
workspaceThumbnail slider, because right now those animations are "glued
|
|
together" using the actualGeometry, so they would get out of sync.
|
|
|
|
The reason there are no errors happening in workspace.js with the
|
|
existing code is that due to a bug in Clutter the fullGeometry of
|
|
WorkspacesDisplay gets set very early while mapping the WorkspacesViews
|
|
(because the overviews ControlsManager gets an allocation during the
|
|
resource scale calculation of a ClutterClone, see
|
|
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1181), so it
|
|
won't be set to null anymore when calling
|
|
WorkspacesView.animateToOverview().
