---------------
gnome-shell (3.34.1+git20191024-1ubuntu1) focal; urgency=medium
* Merge with Debian. Remaining changes:

- quick alt-tab (without showing up the switcher) switch only between
the last window of the last 2 applications to be focused instead of

- Allow user switching when using LightDM.
+ ubuntu/lock_on_suspend.patch

styling by default, not impacting the gnome user session though.

for our ubuntu session. Change it as well here, still applying the
background noise loading.

+ optional-hot-corner.patch
- enable patch proposed by upstream developer already in package (but
not in series) to add a settings for optional hot corner activation.

Title:
Delay launching application launcher gets longer the more apps are
open
Status in gnome-shell package in Ubuntu:
Fix Released
Status in gnome-shell source package in Eoan:
In Progress
Bug description:
[ Impact ]
On latest up to date daily image on my ThinkPad X220 / i7 / 16GB / 150GB SSD.
If I launch a bunch of applications - possibly a slightly unreasonable
number, but a lot anyway - with minimal CPU or memory in use, the button to
launch applications in the bottom left takes progressively longer to run.
Video showing it: https://www.youtube.com/watch?v=BRbFk-n9KzQ
[ Test case ]
- Launch lots of applications
- Click in the applications icon in the launcher (or press super+A)
- Animation should not be delayed (some delay is still expected depending
on the number of installed applications)
[ Regression potential ]
Windows in activities overview might have wrong positioning
This is uploaded under the GNOME MRE:
https://wiki.ubuntu.com/StableReleaseUpdates/GNOME
---
Steps to reproduce.
Open application launcher
Note a ~0.6s delay before the icons fly onto the screen
Open GNOME Software
Install all the editors picks
Launch a bunch of applications
Click the application launcher
Note a 4s delay before icons fly onto the screen.
Expectation
Honestly, no delay at all, but it should be at least consistent with when no
applications are running, so 0.6s delay as per the state when no apps are
launched.
