[ubuntu-dock] App Grid icons out of alignment when opening from overview

[Carwyn Nelson]

Affected version:
Ubuntu 20.04
Gnome Shell Version 3.36.1
Only tested on xorg

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

What did GNOME Shell do that was unexpected?:
Display the App Window icons out of alignment when accessing the app grid via the window overview (pressing the Super key)

What did you expect to happen:
I expected the icons to display properly.

After some further help from the upstream bug ticket it looks like this is an issue with the Ubuntu Dock (dash-to-dock).

If you disable that extension this issue no longer occurs.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Carwyn Nelson (carwynnelson)]

After some further investigation (pulling down dash-to-dock and compiling/running the v68 and v67 tags) I think this issue only exists in the ubuntu dock variant of dash-to-dock.

Bisected. Thanks!

[Daniel van Vugt (vanvugt)]

Also if the problem only exists in ubuntu-dock then there's probably a fix in dask-to-dock v68 already.

[Carwyn Nelson (carwynnelson)]

When I was bisecting git threw me into a few commits that did not have the ubuntu-dock modifications and I was not able to spot the bug in those.

I've tried to see if there is anything obviously broken in the bisected commmit, but my lack of knowledge in gnome extensions means I haven't found anything yet.

I will try and find some time to delve into the upstream dash-to-dock commits and see if the bug existed there, and if so what fix was applied.

[Marco Trevisan (Treviño) (3v1n0)]

I've looked at the bisected commit, but that doesn't seem to help much unfortunately as it was just a merge commit with upstream changes, would be better if you could do it in the master branch.

[Carwyn Nelson (carwynnelson)]

I'll try and find some time this week to see if I can bisect on master.

[Carwyn Nelson (carwynnelson)]

I've tried to see if I can find this bug in dash-to-dock master but if it is there it's like finding a needle in a haystack.

Do you have any advice for how to track this down?

I'm beginning to think that this bug somehow only exists in the ubuntu-dock branch, although I have no strong evidence to support that.

[Carwyn Nelson (carwynnelson)]

@yipchunmun what was the reason behind changing the status of this bug?

[Yip (yipchunmun)]

@carwynnelson I apologize that I accidentally changed the status when I was reading this bug description on my smartphone. I have tried to change it back to a Triaged status, just like the previous status but I am not able to change it. So kindly please change back the status to the status that it supposed to be. Sorry for causing any inconvenience to you.

[Carwyn Nelson (carwynnelson)]

Not a problem.

Marco, please could you change this back to triaged?

This bug is still happening on ubuntu-dock version 68.
If I disable the dock it goes away but re-enable it and it comes straight back.

[plum (plumerlis)]

Same here
Ubuntu 20.04 with lastest dock extension

[Sujit Kumar (therealsujitk)]

Yeah, this bug went away when I disabled ubuntu-dock.

[plum (plumerlis)]

Updated to latest version and this bug still here.
