<something> is not responding window is constantly showing when debugging a program

[Vaclav Cermak]

Mentioned window about no responding program is showing and stealing focus when I try to debug a Java program in Eclipse. When I click on Wait, it disappears for a moment and opens again.

This renders Ubuntu 17.10 with Gnome 3 nearly useless for program debugging.

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

[Alessandro Muntoni (alemuntoni)]

It also affects me when I'm debugging with QtCreator using Ubuntu 18.04, this is very annoying.
When the window appears, it is not possible to click anywhere except that window (also if it is in background), and it is not possible to disable or increase the timer for non responding applications, as pointed here: https://askubuntu.com/questions/412917/how-to-increase-waiting-time-for-non-responding-programs

Hi
same problem here Ubuntu 18.04 QtCreator 4.6.1

it looks like it steals mouse clicks, because keyboard still works

[marun_cz (marun1)]

same problem here
ubuntu 18.04 qtcreator 4.6.1
it looks like it steals mouse clicks because keyboard shortcuts still work

gnome on wayland works fine, that 'not responding" window is still there but i can use qtcreator just fine

[Phil Wolff (adiabat)]

It appears that the dialog is system-wide modal. Is that really necessary? If so, it should also appear on top of *every* window stack in the system, not just the stack containing the offender.

[Bill Robinson (airbaggins)]

I'm getting the same problem debugging Unity Editor. It is unusable. As I start going through breakpoints in Rider, I have to continually switch back to the Unity editor window to say keep waiting. Is there really no other workaround than to recompile the window manager?!

[Joan (jmigual)]

When working with Qt Creator 4.6.2 it happens too and it just makes debugging unusable.

[Bill Robinson (airbaggins)]

To update my own workaround, I have switched to LXDE for now (installed lubuntu-desktop). It's pretty drastic, but it completely sidesteps mutter.

[Adam Divak (adam.divak)]

The same bug affects me on Ubuntu 18.04 LTS when debugging C++ applications using CLion. The fact that the popup can remain hidden in the background but it blocks mouse clicks against all applications (including the foreground ones) is a huge issue, and there is no known workaround for the problem. How do core devs use their own system for application development?

Strangely the timeout between two popups is not constant, sometimes it happens every 5 seconds and sometimes the application being debugged can stay in the background for longer periods without causing this issue.

A similar issue has been reported against Fedora a long time ago and it did not get any attention there either: https://bugzilla.redhat.com/show_bug.cgi?id=981149

Please put this on high priority.

[Dmitry T. (over-9000)]

Same issue. Ubuntu 18.04.1 + Visual Code while debugging OpenGL app. Please increase the priority.

[Eneko Castresana (ecv80)]

Same case: 18.04 debugging Unity3D on VSCode. Really annoying, renders debugger almost useless. I suggest making at the very least PING_TIMEOUT_DELAY (as reported here: https://askubuntu.com/a/701991 ) user configurable through a text file, and preferably add the possibility of configuring it on a per-process name basis. We can't just be switching WM in order to debug. This is ridiculous.

[Jeromy Stroh (jeromyu)]

Still running into this. It's impossible to debug. Ubuntu 18.0.4.1 gdb debugging large application.

[Marwen Azouzi (marwen-azouzi)]

Same issue. Ubuntu 18.04.1 + Visual Code while debugging OpenGL app. Please increase the priority.

[ali ghazi (alighazi)]

Same issue. Ubuntu 18.04.1 + Visual Code while debugging OpenGL app. Please increase the priority.

[karthikjain (karthikjain)]

Same issue while debugging C++ application. Ubuntu 18.04.01 + gcc 8.2.0 + Qt creator 4.5.2.
Please increase the priority

[Sebastien Bacher (seb128)]

Would be worth reporting upstream on gitlab.gnome.org if that hasn't been done yet

[Will Cooke (willcooke)]

Marking as not fixing for release. That doesn't mean this won't be fixed, just that we won't block release on waiting for it to get fixed. This will be picked up in the 19.10 cycle for fixing.

[Andrea Azzarone (azzar1)]

This has already been fixed both in Disco and Cosmic. The commit to be SRUed in Bionic is this one: https://gitlab.gnome.org/GNOME/gnome-shell/commit/b3045cb964459d050c280a4a4958131cfa24ebfb

@3v1n0 Do you want to take care of it or should I do that?

[Marco Trevisan (Treviño) (3v1n0)]

Andrea, if you want to prepare a merge proposal against bionic we can merge it in the VCS for now and then when I prepare the new SRU for bionic with other fixes land it... As you wish

[Marco Trevisan (Treviño) (3v1n0)]

Upstream fix was released in 3.30.1

https://gitlab.gnome.org/GNOME/gnome-shell/issues/273

[Amr Ibrahim (amribrahim1987)]

Three commits got backported upstream to gnome-shell-3.28 related to the close dialog, but after the git snapshot that is being SRUed now to Bionic. The fix to this bug is there.
