Description

Mumble fails to launch - segmentation fault.

Steps to reproduce

  1. Open a terminal
  2. mumble
  3. Segfault

Mumble version

1.6.0

Mumble component

Client

OS

Linux

Reproducible?

Yes

Additional information

  • Using a tiling window manager on Wayland (hyprland).
  • If I remove either window_state or window_geometry from ~/.config/Mumble/Mumble/mumble_settings.json then I can launch mumble again without issue. Closing and attempting to reopen reproduces the issue.

Not sure if this is a Qt, Wayland, or Mumble issue. I have not experienced this issue with other Qt apps, so I figured I would submit a bug report to Mumble. Unsure of a way to enable more verbose logging. Just let me know if I can provide something more helpful.

Did you self-compile Mumble? Or rather: do you think you would be capable of compiling a debug version of Mumble in order to reproduce the issue in a debugger (to get a full stacktrace)?

This is probably similar to #6577

But, as this happens in a loop, Qt and hyprland seem to be disagreeing on what a valid window_state would be. Not sure if we can really do anything about this.

I mean we could simply not restoreState on Wayland...

I would be open to compiling a debug version if it would help you guys. Is there a debug-mode compilation guide somewhere on the github? Maybe using the debug USE flag would be sufficient (https://wiki.gentoo.org/wiki/Mumble). I will try recompiling with that flag tonight and see if the backtrace is any better.

Yea this seemed hyprland specific -or maybe specific to a dynamic tiling window managers. "Traditional" wayland Desktops Envs may not have this issue since Qt can spawn the window at any position on top of other windows. I wouldn't suggest disabling restoreState on wayland altogether.

I wonder if having the Server > Connect window that opens on launch be modal/attached to the main window would resolve it (I'll poke around to see if thats already an option, or see if I can disable that window on startup).

I wonder if having the Server > Connect window that opens on launch be modal/attached to the main window would resolve it (I'll poke around to see if thats already an option, or see if I can disable that window on startup).

Interesting idea, it should™️ be the case that only the MainWindow state is saved. But, it could very well be the case that some other window, modal is the culprit. Maybe including a race-condition somehow usually not found on the classic compositors?

I was able to build 1.6.0 on Gentoo from the git repo and reproduced the issue.

# needed to compile these extra libs
emerge app-accessibility/speech-dispatcher
USE="mdnsresponder-compat" emerge net-dns/avahi

Turned off support for libs that would take too long to compile and not related to the issue

cmake -B build -Dsymbols=ON -Denable-mysql=OFF -Denable-postgresql=OFF -Dice=OFF

Doesn't look more helpful than the original stacktrace to me... Is there somewhere else I should be looking for more debug output?

Something maybe noteworthy that I've reasoned out - I am only able to reproduce the issue under a specific circumstance. I have 2 monitors laid out like this:

 _______
|       |  ___________
|       | |           |
|   A   | |     B     |
|       | |___________|
|_______|
  • Launch mumble from the terminal on monitor B
  • mumble opens on monitor B
  • Move the mumble main window to monitor A
  • Close mumble
  • Launch mumble from any terminal
  • Segfault

You can swap A and B in the explanation and the same issue occurs.
Maybe window_geometry and window_state are not "synced" with each other? One gets updated on launch, one on close, and that causes some kind of freakout? Not really sure what to make of it... that's just my first thought.

Here is the current state of those params in the config.

        "window_geometry": "AdnQywADAAAAAAAA///92gAAA70AAAHtAAAAAP///doAAAIZ////rgAAAAACAAAABDgAAAAA///92gAAA70AAAHt",
        "window_state": "AAAA/wAGBNn9AAAAAgAAAAAAAAEAAAAD1/wCAAAAAvsAAAAMAHEAZAB3AEwAbwBnAQAAAD0AAAO7AAAAegD////7AAAADgBxAGQAdwBDAGgAYQB0AQAAA/wAAAAYAAAAGAAAABgAAAACAAAAAAAAAAD8AQAAAAH7AAAAJABxAGQAdwBNAGkAbgBpAG0AYQBsAFYAaQBlAHcATgBvAHQAZQAAAAAA/////wAAAFcA////AAACugAAA9cAAAAEAAAABAAAAAgAAAAI/AAAAAEAAAACAAAAAQAAABoAcQB0AEkAYwBvAG4AVABvAG8AbABiAGEAcgEAAAAA/////wAAAAAAAAAA"

First run

mumble opens
move main window to another monitor
then close main window
