Frequently crash the program to be typed in under sway

oxalica commented 1 year ago

Describe the bug Fcitx5 frequently (about 5 times per day) crash the program when typing Chinese using RIME in telegram-desktop or nheko.

To Reproduce Steps to reproduce the behavior:

Open telegram-desktop or nheko.
Typing Chinese using RIME.
Occasionally, the program to be typed in would crash.
For programs not using fcitx5 and only typing in English (firefox for me), they never crash.

wengxt commented 1 year ago

is it a new issue? What's the actual error of telegram-desktop in console?

wengxt commented 1 year ago

backtrace feels like a qt bug to me actually.

wengxt commented 1 year ago

I found very similar back trace that's unrelated to fcitx, but also qt wayland

https://bugs.kde.org/show_bug.cgi?id=450003

This backtrace seems to contain more information. I'll see if I can figure out the bug in Qt. I guess no other people hit this because other doesn't enable assert.

At the same time, I suggest you to create a debug build of qtwayland to have more information.

oxalica commented 1 year ago

is it a new issue?

No. Sorry but I can't remember the accurate time when I first hit it. Maybe more than one month ago I guess.

What's the actual error of telegram-desktop in console?

I usually don't open it in console so I don't know.

I'll see if I can figure out the bug in Qt. I guess no other people hit this because other doesn't enable assert. At the same time, I suggest you to create a debug build of qtwayland to have more information.

Thanks for the information. I'll try to reproduce it with debug tomorrow.

oxalica commented 1 year ago

Oh I got the console output,

telegram-desktop: ../src/wayland-client.c:230: wl_proxy_unref: Assertion `proxy->refcount > 0' failed.
zsh: IOT instruction (core dumped)  telegram-desktop

The related line is this which itself seem unhelpful. Since the assertion is in libwayland, I doubt that if debug build of qtwayland would provide more info.

wengxt commented 1 year ago

@oxalica I discussed with another kde people and we think this is a qt bug, a double free caused by unprotected multithreaded access. Will send a fix to qt later.

With this patch applied, the issue never appears again up to now. Thanks!
