Window borders and shadows missing from GTK3 dialogs (if autologin is enabled and Xorg is used)

[florin]

I have a fresh Ubuntu 24.04 instalation and some of the windows have a few problems. Some are probably caused by theming, as the windows' borders (or their color) makes them impossible to discern from the background windows.

Just earlier I discovered another bug, related to detecting the click and window I clicked. I am trying to see the sub-content of a software update but the system reacts as I clicked the window below. In the recording you can see this happening both with the Terminal and with Firefox.

I have plenty of screenshots and also a screen recording that show the bugs.

Here is a compilation of 4 screenshots I made. It shows the theming problem (I think).

Thanks for the bug report.

Firstly please open a separate bug about the clicking issue (although it sounds related to bug 2063831). We need each bug report to only describe one problem.

For the window borders issue please try:

1. Deleting all local extensions:

   cd ~/.local/share/gnome-shell/
   rm -rf extensions

   and then log in again.

2. If the problem still isn't solved then try resetting to system default settings:

   dconf reset -f /

   and then log in again.

3. If the problem still isn't solved then please run:

   journalctl -b0 > journal.txt
   dconf dump / > dconfchanges.txt

   and attach the resulting text files here.

I'm also affected by this bug. Log out and log in again fixes it, but after restarting the system it's broken again. Apps like transmission, vlc, libreoffice are affected. Nautilus, Rhythmbox or terminal have borders and shadow around it looking as it should.

I recently upgraded from Ubuntu 23.10 to Ubuntu 24.04 and encountered this issue. When this issue occurs, I found that I couldn't resize windows by dragging the border, and the area near the border became unresponsive, redirecting my focus to the window behind it upon clicking. Notably, this issue seemed isolated to gtk3 applications such as Intellij IDEA and VMware Player.

I have also encountered this issue. Also QT and Electron applications have no border/shadow.

I've noticed something, maybe this will help: all windows with SSD don't work properly, windows with CSD work as expected. Firefox main window with CSD works, sub-windows without don't.

[Vitaly Akulin (n1gt)]

I have also encountered this issue when autologin enabled. Also Telegram (flatpak) and GIMP applications have no border/shadow, and I couldn't resize windows by dragging the border. Log out and log in again fixes it, but after restarting the system it's broken again.

[florin (florin-arjocu)]

If it helps, I also have autologin.

[Paulo Narciso (p-narciso1979)]

Me also.

[David (david431)]

I don't use autologin.

Hi, just to report: I've upgraded from Ubuntu 23.10 to Ubuntu 24.04, the first solution, proposed above by Daniel van Vugt (vanvugt), resolves the issue for me.

[Claudio (claudio-fischer)]

same problem here. Did a fresh install of Ubuntu 24.04.
After using autologin a lot of programs have no border and shadow.
They also cant be resized any more.
If I log out and in again, this effects are gone.
After a restart with autologin the effects are here again.
If I disable autologin, everything works fine.

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

@Daniel

I can reproduce these both in xorg & wayland, tested on intel and AMD graphics

its autologin that somehow trigger this, when autologin off or logout/log back in

i can resize windows again

[bl (blagopoluchie)]

Fresh installation of 24.04 on PC.
The bug in the Double commander (both QT6 version and GTK2 version), also in the Gnome commander (GTK+) file managers.

Logout removes all these 3 bugs (resizing, shadows, and https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/2063831 Clicking on bottom half of applications switches to background), but only until reboot.
Disabling autologin seems to help.

[Bernard Robbins (bernardrobbins)]

Logging off and on again fixed the issue with me. I have autologin on. Effects Thorium Browser but not Chrome. Also effects my Slack install, but no other apps so far.

I turned off auto-login. Logging in as soon as the user login prompt appears will cause the resizing issue. Waiting a bit after the login prompt appears to log in will not cause the window resize error.

Ubuntu 24.04 LTS upgraded from 23.10.
mutter-common/noble,now 46.0-1ubuntu9

[Ljubomir Buturovic (ljubomir-9)]

Affects Emacs (i.e., makes it unusable). Disabling autologin solves the issue for me.

[Carlos Ramos (carlosrges)]

Same problem here. Affects some apps like VS Code, LibreOffice... But not others like Firefox or Nautilus. Using Xorg and NVIDIA drivers. Never turned on autologin.

[Daniel Buchmann (bukbr)]

Same problem here too, affects ZapZap and Yuki

[Enorize (enorize)]

I also encountered the same issue. The affected software from the official software sources includes GParted and Software & Updates (Software Updater). Third-party software includes Zotero, Electron-based software such as Typora, etc.

I also noticed another issue that might be related to this:

When there are other normal windows in the workspace, clicking on certain areas of the affected software causes it to minimize or invisible.

Steps to reproduce these issues:
1. Open Chrome and make it full screen
2. Open Software & Updates, there is no shadow on the window edges
2. And click near the edge(for example, click on the blank area to the left of the 'Close' button. ), and the Software & Updates window becomes invisible or under the chrome window.

autologin is enabled and Xorg is used

[florin (florin-arjocu)]

I wonder if the lack of borders does not cause the click problem. Probably the click is calculated within the border and while there are no borders, there is a problem so the click goes to the lower window/object. There is quite a while without a solution, it is quite annoying.

[Eimis (eimantas-es)]

This issue affects me, too. Whenever I try to use a newer kernel installed via Mainline app this issue occurs, using the default kernel works fine. ---I have no autologin enabled.---

I have tested and can confirm that logging out and back in works and does solve the issue somehow.

[goat (goats)]

Any update on this? Its long time since first reports... I am affected with this one too, it make OS not usable at all. In my case bug exists on VS Code.

[Luis Alvarado (luisalvarado)]

While this is being investigated and a fix will be pushed, by disabling auto login (For the moment) fixes the issue.

[Mikko Kortelainen (kortsi)]

This affects me, too. Some apps have borders missing. I am unable to resize apps from the lower right corner. Using super+middle I can resize windows, but if a resize the window larger, the newly exposed area of the window seems to send clicks through to the window below.

At least these apps are affected:

spotify (snap)
chromium (snap)
slack (snap)
code (snap)
gimp (snap)
vim (deb)

For vscode it helps to use custom windows decorations.

For chromium it does not matter if native or custom window decorations are used.

I have also chrome installed (same version as chromium) using deb. It has no problems.

I'm on wayland. I have autologin enabled. Logging out and in again fixes the problem.

[robert (robert-hans)]

It seems like Regional Formats or language problem to me.
I installed new Ubuntu 24.04 in English (US) and the windows worked fine.
When I changed Regional Formats to Korean and reboot the system, the window problem started and remains.

I think the password/login process in Ubuntu has a problem with cjk language.
In Ubuntu 22.04, I installed 4 languages (English, Russian, Japanese, Korean), and whenever the login prompt appears, there were only English and Russian available.

In addition, I had to change the input language because the default language was set to Russian in the prompt no matter what the language order.

I think someone needs to test the backport suggestion made by upstream:
