Ubuntu 20.04 QA-test; using daily on
hp 8200 elite sff (i5-2400, 8gb, nvidia quadro 600)

I saw https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1869571 last night on #ubuntu-bugs-announce, and I think this box maybe has similar screen setup, so I thought I'd do some general play, then look for bug.

adjust displays to match my setup (one monitor above other; what settings describes as monitor.2 is my lower, also mark the lower (was right) as my primary display)

on opening menu however - icons come out but quickly disappear (or could be described as come out from bottom right, shrink (below date on top panel) then disappear ??? it's very quick but menu is un-operational as per https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1869571

Of note - the Frequent-All heading keeps jumping as if being re-drawn constantly. However this wasn't always visible, but if left at the menu position (where no options are shown) the shaking becomes rather obvious but only images "Frequent All", happening whichever is underlined (orange) and keeps shaking when I move mouse.

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

More detail from #8 test, I had closed the 'displays' setup, and of course could no longer select anything from applications when clicked (no icons in selection), but search bar does work; so I used the search function.

Results in a tiny scroll area which isn't high enough to fully display "Displays Choose how to use connected.." but is close.. I can scroll down/up in the tiny window.

Also by entering a single letter (search function) I can have some icons appear for selection, selections work but icons are larger than window so it requires a fair amount of scrolling. My findings are exactly as per OP (except I have default Ubuntu 20.04 background), and a few apps (firefox, nautilus, ..) opened in my upper display from earlier QA-testing..

This bug has been reported on the Ubuntu ISO testing tracker.

Please report the problem to the upstream developers at:

  https://gitlab.gnome.org/GNOME/gnome-shell/-/issues

and then tell us the new bug ID.

I have reported this problem on the gnome-shell gitlab, new bug ID is 2528.
https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/2528

I also filed as https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/2529

Sorry Jarno, your filing wasn't present when I looked, though i got called away.. so it was awhile between start & finish of filing.

I didn't notice to mention this earlier as I had no windows open on the top monitor at the time of writing, but it is fair to mention that the top monitor's app overview works flawlessly, only the bottom monitor is broken. Attached picture for clarification.

the same is happening to me.

Same happening for me, with two rows of screens, three on top two in the bottom row.
Primary is top left.

Overview of the affected layout

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

Tracked upstream with further information: https://github.com/micheleg/dash-to-dock/issues/1136 but should be resolved before release since Ubuntu Dock uses setting "Panel mode: extend to the screen edge".

Hi, this issue happens to me to. But I figured it out that this only happens in vertical multi-monitor setup with the dock on the left or on the right. If I move the dock to the bottom, the issue disappears. So that could be a temporary workaround for you until this bug is solved.

WORKAROUNDS:

* Run 'Extensions' (from package gnome-shell-extension-prefs) and disable 'Ubuntu Dock'. You will get the regular GNOME dock instead; or

* Settings > Appearance > Dock > Position on screen = Bottom; or

* Arrange your monitors differently :)

https://github.com/micheleg/dash-to-dock/pull/1174

I just ninja'ed the docking.js file as per the change in comment #23 and that fixes both the issue in this bug, and the issue where the icons are all small (as shown here https://www.youtube.com/watch?v=2mZZtClVOSg)

Screenshots attached.

This bug was fixed in the package gnome-shell-extension-ubuntu-dock - 67ubuntu20.04.5

Hi, I decided to add information here rather than creating a new bug report. I'm in dual screen too, main screen at left (32"), secondary screen (19") at right and in portrait mode (rotated right). The window are improperly growed : they extend from full main screen to half the "witdh" of the secondary screen. Additionnally, the « pop-up » menus (eg. from settings) do not appear at the right place (see screen capture attached). This is very annoying !

Argh. Just forgotten : the problem of window extending out from its natural place disappear if I revert the orientation of secondary screen from « portrait turned right » to « landscape ».

Re-argh : my Ubuntu 20.04 is fully up to date.

This bug is closed.

I do have gnome-shell-extension-ubuntu-dock in version 67ubuntu20.04.5, but still got "my" problem. Should I fill a separate bug report ? And sorry for the pollution-by-comments :-(

Yes, please report a new bug by running:
