Apps grid is invisible on Super+A
Affected version (see screenshot below)
Bug summary
When I press Super+A, app icons are not showing up. Actually they seem to be invisible because I can still click on where a specific app would be. When I click the dots menu from dash-to-dock app icons grid appear normally although there is a flickering effect that shouldn't be present.
Steps to reproduce
It's reproducible to my machine when I press the Super+A shortcut. See screenshot below
