App Grid icons out of alignment when opening from overview

[CarwynNelson]

Originally raised on the gnome gitlab and after some debugging this bug looks like it originates in dash-to-dock. I have also raised this in launchpad.

Affected version

• OS: Ubuntu 20.04
• Gnome Shell Version: 3.36.1
• Display Server: Only tested on xorg
• Dash to dock version: 67

Bug summary

When opening the App Grid (aka "Show Applications) from the window overview (I don't know the technical terms) the icons shift out of alignment. This gets worse if you have multiple pages of apps (as I do), and it gets even worse the more you open and close the App Grid in this manner.

I cannot see the same bug if you just open the App Grid from the desktop.

Steps to reproduce

1. Open the overview window using the Super Key
2. Click the "Show Applications" icon
3. You will see the icons in the App Grid shift downwards
4. Scroll down to see the icons move further out of alignment

Relevant logs, screenshots, screencasts etc.

After some further investigation it looks like this only impacts the ubuntu-dock variant of dash-to-dock. I have updated launchpad to reflect this.

After doing some git bisecting I believe I have tracked the bug down to this merge commit d322443.

@CarwynNelson mh how the dock can even run without that commit?
Or well work properly?

I'm not quite sure. Are you able to replicate the bug on your machine?
