[bug] Launcher not responsive for a second after exiting an app

[vvvvvv01]

Describe the Bug

Hey, back with a new phone a new problem :)

Whenever I return to the home screen the Launcher doesn't "start" for a quick second. The clock doesn't display and gestures aren't registered
Disabling battery optimization/background limits didn't help.

Expected Behavior

Launcher is available immediately when exiting an app

To Reproduce

1. Open any app
2. Return to home screen

Your Device

Thanks for reporting!
Does this also happen when using three button navigation instead of gesture navigation?
Do you know how to obtain a log?

[vvvvvv01]

It does not happen with three button navigation, only gestures.
I vaguely know how to use logcat but if there's an easier way feel free to let me know.

Here's what I got from logcat
