Comment 0 for bug 1848009

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.

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.
