Please install the binary with crash reporting system from https://desktop.telegram.org, enable crash reports by enabling installation of beta versions in advanced settings, reproduce the crash, copy the report tag (not the user tag!), send the report and post the tag here.

The same with the second :( I don't know how to debug that.

john-preston · 2023-02-15T07:57:33Z

@socketpair

I see strange lines in the dump reader log, like:

Can you please try putting the downloaded binary to /home/mmarkk/Telegram/ folder? Just in case this is the reason and it doesn't handle such paths too well. Then reproduce the crash once again and send the report once again and post the report tag once again.

socketpair · 2023-02-15T13:29:38Z

socketpair · 2023-02-15T13:30:26Z

Okay, I will try to put to another folder. Anyway, if Russian folders do not work—it's also a bug

socketpair · 2023-02-15T13:43:11Z

Sometimes Telegram icon disappears in list of applications in ALT-TAB switching. No messages in log and no crashes. Next pressing ALT-TAB shows the icon again.

Everything seems fine on 4.6.2 Flatpack.

I have no access to crash dumps, you have to wait @john-preston

ilya-fedin · 2023-02-15T18:27:28Z

Maybe it's because we have a static copy of libffi in the binary... Does flatpak package segfault as well (it may exit, but not segfault)?

socketpair · 2023-02-15T21:08:39Z

Flatpak, rpm and official -- all three crash. But possibly by different reasons. I need to figure out.

Please help how to debug official build. I can even send core dump after logging in by second account with 2fa. No sensitive data inside, and 2fa guarantee no one can take my account.

ilya-fedin · 2023-02-15T21:29:57Z

@socketpair the last crash dump from Engllish dir shows that it crashes in Qt's checkWaylandError function, going to some function in libwayland-client.so.0, then a loop of libwayland-client.so.0-libglib-2.0.so.0-libffi.so.8 going multiple times and crashing somewhere in shared_ptr.h in Telegram binary (as libstdc++ is linked statically). I suspect that Qt should show a error instead of crashing (and then do exit(1)), but something apparently is wrong with library linking in static binary, so it crashes before returning from libwayland function back to checkWaylandError, possibliy due to a static copy of libffi linked in the binary. And I see no other way of checking that theory than checking whether flatpak package crashes as well or just exits abnormally.

socketpair · 2023-02-17T09:47:36Z

Crash ID: 9a233aff-419b-4956-c5967894-2875c3d0

New version. Still crashes.

ilya-fedin · 2023-02-17T13:30:59Z

@socketpair I've asked you to check the flatpak package in details

socketpair · 2023-02-17T13:41:39Z

Crash ID: 30c12824-696b-4bf2-36ad13b9-d81d5f5c (it's official build). Again after qt.qpa.wayland: Creating a fake screen in order for Qt not to crash.

Okay, will try Flatpak version. How to enable crash-dump sending in it. The same ? Hope yes.

socketpair · 2023-02-24T12:36:39Z

@ilya-fedin Yes, but I think it's not because of some parallel access from TG. If it is about threads—I think we are speaking about threads inside qt-wayland. But anyway, I will test.

And no, I run memtest on my laptop.

Possibly, it better to communicate in telegram @socketpair and not in github chat. Feel free to write me.

ilya-fedin · 2023-02-24T12:55:20Z

Yes, but I think it's not because of some parallel access from TG.

Huh? It's parallel access in qtwayland code, it has a separate event thread, so access to the same variables happens from both qtgui main thread and qtwayland event thread.

ilya-fedin · 2023-02-24T12:57:30Z

Actually it really dies. What a crap! so wit your binary, wayland crashes itself. What can I do next ?

Some bug in GNOME now apparently

socketpair · 2023-02-24T13:06:57Z

@ilya-fedin I know, you don't like Gnome, but why you decide it's a gnome bug? Without running your TG version, there were no crashes of wayland. I think bug in wayland so.

ilya-fedin · 2023-02-24T13:10:41Z

@socketpair client shouldn't be able to crash the compositor, if the compositor crashes, it's solely the compositor's bug.

"Bug in wayland" means "bug in xml files" as Wayland is just a spec written in xml files. GNOME Shell / mutter is your implementation of it.

socketpair · 2023-02-24T13:48:41Z

@ilya-fedin I can test not in Gnome. Just say what to do. Sway? What compositor to use?

ilya-fedin · 2023-02-24T14:06:05Z

I use Plasma, but I guess that's GNOME-specific

ilya-fedin · 2023-03-01T17:49:32Z

4.6.6 beta uses Qt 6.5.0-beta3 (only static binary and snap)

ilya-fedin · 2023-03-02T17:46:11Z

I treat the silence as the issue being fixed

socketpair · 2023-03-02T18:54:52Z

@ilya-fedin now even official version crashes wayland :( dunno what to do.

ilya-fedin · 2023-03-02T18:57:57Z

Right after Telegram launch?

socketpair · 2023-03-02T19:40:16Z

@ilya-fedin no. When screen locking starts. In my configuration (actually nothing special)

ilya-fedin · 2023-03-02T21:31:26Z

Ok, I feel this is going to be a long-standing issue

socketpair · 2023-03-13T14:08:05Z

gnome-shell[660893]: segfault at 0 ip 00007fd2eda73709 sp 00007fff0f6cc3f0 error 4 in libwayland-server.so.0.21.0[7fd2eda71000+8000] likely on CPU 0 (core 0, socket 0)

@ilya-fedin It falls regularly. On EVERY screen locking. ONLY when Telegram is running. Definitely somewhere not in Telegram, but who should I complain ? Gnome-shell ? Wayland ?

ilya-fedin · 2023-03-13T14:09:34Z

gnome-shell or mutter

https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/6503

ilya-fedin · 2023-03-18T08:32:32Z

The flatpak package of version 4.6.12 beta in flathub-beta got Qt 6.4.2->6.4.3 update that should have the fix for unprotected multi-thread variable access as well, you can try it if you want, maybe it won't crash entire session like 6.5.0 does. It should be available in multiple hours.

socketpair · 2023-03-18T08:55:38Z

@ilya-fedin seems the problem not in threading at all: I have reported the bug, but they say it's the same as this: https://gitlab.gnome.org/GNOME/mutter/-/issues/2570

ilya-fedin · 2023-03-18T09:02:53Z

Well, it's partially in threading as Qt 6.4.2 crashes due to memory corruption before sending a reply to the compositor that causes compositor's crash due to the compositor's bug.

Paval-from-Belarus · 2023-04-21T19:54:44Z

Don't know, it's correct topic or not, but Telegram still crashed on fedora 37 by launching wallet in chat (has loading few seconds and suddenly crashed)

ilya-fedin · 2023-04-21T23:19:46Z

What is 'wallet in chat' and how is that related to screen locking?

Paval-from-Belarus · 2023-04-22T09:04:50Z

Nothing common with screen locking (but it's supposed to be similar issue). Simplify, trouble with popup window over Telegram. Should I open new issue?

ilya-fedin · 2023-04-22T09:18:46Z

I don't quite understand what "trouble with popup window over Telegram" means, but if screen locking is not involved then it doesn't sound like a similar issue. After all, this issue is about GNOME itself crashes (and the issue creator thinks Telegram is causing it, although I don't agree), not Telegram.
