Arch Linux

Same problem here.

I'm using nouveau with xwayland and gnome-shell

crashbit@gt62vr-6re ~]$ telegram-desktop

(process:4054): Telegram-WARNING **: 16:07:01.475: Unfortunately, GTK integration conflicts with qgtk2 platformtheme and style. Therefore, QT_QPA_PLATFORMTHEME and QT_STYLE_OVERRIDE will be unset.
Telegram-Message: 16:07:01.477: This can be ignored by setting TDESKTOP_I_KNOW_ABOUT_GTK_INCOMPATIBILITY environment variable to any value, however, if qgtk2 theme or style is used, this will lead to a crash.
Telegram-Message: 16:07:01.477: GTK integration can be disabled by setting TDESKTOP_DISABLE_GTK_INTEGRATION to any value. Keep in mind that this will lead to clipboard issues and tdesktop will be unable to get settings from GTK (such as decoration layout, dark mode & more).

(process:4054): Telegram-WARNING **: 16:07:01.477: Application was built without embedded fonts, this may lead to font issues.
Warning: Ignoring XDG_SESSION_TYPE=wayland on Gnome. Use QT_QPA_PLATFORM=wayland to run on Wayland anyway.
Telegram-Message: 16:07:01.605: You can disable tray icon counter with TDESKTOP_DISABLE_TRAY_COUNTER and make it look better if it is monochrome.

qt.qpa.xcb: xcb_shm_create_segment() failed for size 3346112
The X11 connection broke (error 2). Did the X11 server die?
Violació de segment (s'ha bolcat la memòria)

Same problem.

These are my relevant .bashrc lines:
export QT_QPA_PLATFORM=wayland-egl
export QT_WAYLAND_FORCE_DPI=physical
export QT_STYLE_OVERRIDE=gtk2
export WAYLAND_DISPLAY=wayland-0

It broke for me on Gnome (Wayland session, works on X11) after updating `xorg-server-wayland` to 1.20.9-1. If I downgrade to 1.20.8-3 then it works.

somody: Telegram runs on X11 and ignores QT_QPA_PLATFORM unless you specify TDESKTOP_I_KNOW_ABOUT_GTK_INCOMPATIBILITY (you can actually see the information about this variable in the crashbit's message above).

I confirm. Telegram runs with Gnome X session, and fails with Wayland session.

The problem arrived after after today update of xorg-server-* packages.

It starts normally when I clean `~/.local/share/TelegramDesktop`, but fails again after the successful login process.

The only error messages are three "error: : cannot open"

The upstream issue: https://github.com/telegramdesktop/tdesktop/issues/8506

So hang on, I'm a little confused. We know that 2.3.2 always works on X11 and always fails on Wayland and it appears to be a problem of xorg-server-wayland?

Does any combination of compile flags or env vars make it work for any of you guys on Wayland?

Svenstaro, It works with environment variables QT_QPA_PLATFORM=wayland and XCURSOR_SIZE=24

I confirm a bug. Also on telegram 2.3 I have a bug with cracking sound on all system when the call starts. Does anyone have the same?

Let's not conflate bugs, please! Make a new bug in our tracker in case you have reasonable cause to assume this new bug to be a packaging issue.

For the actual issue: This also seems like an upstream bug to me as I don't see any reasonable option for us to set. We could do some downstream patching but it seems to me we should rather make sure this is properly handled upstream.

This is the corresponding upstream bug:
https://github.com/telegramdesktop/tdesktop/issues/8506

And this is the bug report for the xserver:
https://gitlab.freedesktop.org/xorg/xserver/-/issues/1072

Same issue here. I revert https://github.com/freedesktop/xorg-xserver/commit/5c20e4b834145f590c68dbc98e33c7d3d710001a and telegram works again.
The "QT_QPA_PLATFORM=wayland" workaround only works with "Client-Side Decorations Initiative"(Turn off Telgram setting->Advanced->System integration->Use system window frame).

I think we're going to wait this one out and see which upstream wants to fix this.

https://github.com/telegramdesktop/tdesktop/commit/6635d03818c90f62cfddb516acadc293255b8905

This should fix the issue!

2.3.2-2 should be good, please test.

2.3.2-2 works. The issue is fixed.

Thank you!
