Sway sometimes segfaults when closing VSCode window

[eternal-sorrow]

• Sway Version:

  • 1.8.1

• Debug Log:
  I didn't get a debug log for this. If you need it, I can try to get it.

• Configuration File:
  I didn't try to reproduce with default configuration, but I can try it if needed.

• Stack Trace:

• Description:
  1. Start VSCode as a native Wayland application.
  2. Close the application window with a keybinding.
  3. Sometimes (not always) sway crashes.

I started seeing this since the 1.8 update. I thought it's #7303, but then 1.8.1 came out with a fix of that issue, and crashes sometimes happened even after this. I was trying to get a stacktrace for some time, but for some reason I was unable to install the debug symbols correctly on my system, so gdb stacktraces did not contain any useful information.

Now I was finally able to get a meaningful stacktrace so I'm reporting this as @bl4ckb0ne asked me.

[bl4ckb0ne]

Very odd stacktrace, why is it removing the keyboard?

Seems to be more of a wlroots crash (happens here 1). Can you share the sway debug logs?

[eternal-sorrow]

Not today, but I will try to get it tomorrow.

When trying to brute force the crash, I was unable to reproduce this exact stacktrace. But several different crashes happened instead. The one that happened most often is this:

But it happened when starting VSCode, not when stopping it (after several starts and stops it eventually crashes).

[bl4ckb0ne]

The piece of code in wlroots from that stacktrace has not change in a while, could this be a client error taking the compositor down? Would you be able to get any kind of log/stacktrace from VSCode?

[eternal-sorrow]

has not change in a while

And I'm getting this kind of crash for a while (since sway 1.8 update).

could this be a client error taking the compositor down?

I know that when sway crashes with an abort (like in #7506 (comment)), VSCode also dumps core. But I did not look into it. I install VSCode form flatpak and I'm not sure if I can install debug symbols for apps in flatpak.

When sway segfaults, VSCode does not dump core.

Would you be able to get any kind of log/stacktrace from VSCode?

WAYLAND_DEBUG=1 log maybe?

[eternal-sorrow]

For some reason launching VSCode with WAYLAND_DEBUG=1 does not produce any log.

[eternal-sorrow]

This crash happened not when closing VSCode, but when I was working with Steam app:
