vulkan/SDL3 application crashes all of gnome

nspattak · 2025-03-17 20:32:01

Hi everyone,

I have been having this very weird behaviour that i have no idea what to do about. I am working on porting a vulkan/SDL3 application on linux.
I have progressed quite well but at some point it might crash taking down all of my gnome WM and getting me back to the login screen!

I am not asking for help fixing the application (something is wrong in vulkan/scene objects), what i am trying to understand/fix is how is it possible that a user applicatiion crashes the window manager.

Any ideas/pointers are welcome, thank you

Wayland applications that crash are known to often take the whole environment down with them , and gnome appears to be very susceptible to this .
Are you running gnome on wayland or X ?

This could also be a way more trivial bug in gnome:
Client does something with the window, windowmanager cannot deal gracefully with that, WM crashes (bug in the WM)

Since in gnome as much functionality as possible is stuffed into one process and 3rd party extensions are provided by monkey-patching some javascript (executed in that process), some bug in some taskbar extension might crash the session and the display server…
Also gtk recently added a fatal assertion that has caused multiple "core gnome applications" to crash, https://gitlab.gnome.org/GNOME/gtk/-/me … uests/7836

=> Check the system journal and also https://wiki.archlinux.org/title/Core_d … _core_dump for what actually crashes.
Notably your client "crashing" in response to losing contact to the display server (common client/toolkit strategy on X11 and wayland, though unnecessary on either server) is an option, too.

Hi guys, thank you very much for your answers! (sorry for the late reply)

Yes, i am running gnome on wayland.

Also thanks a lot for the reference to coredumpctl, i did not know that. However I already know that my app crashes, it doesn't offer me any new info.

I know my app is broken, i need to fix sth in vulkan initialization. I am surprised that issues in a single app can take down the WM! I mean, come guys, i have been making fun of w95 for the last 30 years and now here we are?

The coredumpctl check wasn't about your app, you want to see why gnome is crashing.

Not so much "a WM", but in general clients can of course trigger bugs in WMs.

Please correct me if i am missing sth obvious but it seems pretty clear to me that a sync list semaphore is causing a crash in my app:

Nobody doubts that your process is crashing, but if gnome crashes along, it's the gnome-crash backtraces you want to look at to understand *why*.
Gnome crashing being the cause of your process crashing was just an extreme example of what the situation also might look like, but you'll *have* to look at the actual gnome crash to understand it.
