Thanks for reporting the issue! However, I really hate to "works on my machine" but it really does, so to help figure out what's different about your setup, can you share your telegram use flags? (emerge --info telegram-desktop) Also, to rule out any upstream issues, can you test the official binary? (https://updates.tdesktop.com/tlinux/tsetup.2.8.11.tar.xz) If that doesn't work either, can you test 2.9.0? If that *does* work, we'll have a very fun debugging session... Thanks for picking this up, I will keep you updated once something has changed.
"emerge --info telegram-desktop" tells me:
emerge --info telegram-desktop

net-im/telegram-desktop-2.8.11-r1::gentoo was built with the following:
USE="X dbus gtk hunspell spell -enchant -wayland -webkit" ABI_X86="(64)"
I have to admit, after two world updates I cannot recreate this issue anymore. I am sorry for the trouble but it was really existing also when I tried to unmask version 2.8.11-r1 in the past. But right now it looks like it was heen fixed for an unknown reason. Thanks for your support! No problem. It's good to get reports of even intermittent issues, as I have more information to work with in case someone reports it again, so thanks. Feel free to reopen this bug report if you encounter the issue again. Unfortunately I is happening again. It seems to be that the probability is lower that before but the issue is not gone: kernel: telegram-deskto[4255]: segfault at 7fe5906ce6a0 ip 00007fe5906ce6a0 sp 00007ffd8aadfac8 error 15 It was happening under the same circumstances then before. That's a shame to hear. Can you try running the official binary (as linked before) or 2.9.0 for a while, and see if it's completely fixed with either of those? This sounds like a race condition of some kind (especially given your mention that high system load "fixes" it), and debugging it will be a pain. Knowing at what address it crashes is kind of useless, but if neither of the above solve it, making a coredump after the crash and/or contacting upstream would be the next step... I will try version 2.9. BTW: I will be on vacation for the next week. Now testing 2.9, it looks good so far. Give it some time to verify that the crashes are gone. Thanks for testing, but I'll give it a bit before declaring victory. Also, can you share your jemalloc USE flags and CFLAGS? My jemalloc currently has no USE flags enabled, so maybe that's the issue. I found an issue on the github that might be related: https://github.com/telegramdesktop/tdesktop/issues/16673 Do you think it's the same as yours? Also don't worry about it, if you're not available to test, I'm willing to wait. Created attachment 731812 [details, diff]
Disable jemalloc
Also in case the issue still happens, it might be worthwhile to try the patch I've just attached. Copy it to /etc/portage/patches/net-im/telegram-desktop.
Using jemalloc prevents telegram from allocating more memory than it really needs, which for some reason seems to be an issue with the glibc allocator, so you might see higher memory usage.
Sorry for pinging this thread, but for anyone having this issue, it'd be nice if they could post the ~/.local/share/TelegramDesktop/log.txt after the crash. I am now running Version 2.9 and it seems to work flawless. Nevertheless, if you like me to do so, I will go back to net-im/telegram-desktop-2.8.11-r2, which became stable in the meantime. Regarding the bug "stack smashing detected" - it does not seem to do with that since I never saw this string in my syslog after the crashes. I see. The stack smashing detected thing depends on your compiler settings, such as GCC's USE=ssp, I'm sure some distros have even stricter defaults where this may trip over just a regular segfault, so I'm not sure it's something different. 2.8.11-r2 is mostly a change in ebuild dependencies, I highly doubt it fixes this issue, so don't bother. Since I have no methods of reproducing this intermittent issue, I'll assume this issue is fixed when >=2.9.0 is stabilized, unless it starts happening again to you or someone else. I was too fast - just right now I got a crash under the same circumstances: Aug 14 13:43:49 kellerkind kernel: traps: telegram-deskto[4301] general protection fault ip:7f9f624f576c sp:7ffeb9e4f380 error:0 in libQt5Gui.so.5.15.2[7f9f621f8000+367000] But it´s likely not happen very often. It will be difficult to find the root cause unless I will install a debug version and write dumps. Unfortunaltly I amd to very experienced in these stuff. My dev experience is more or less python based. Now it happened when opening a video, too. Therefore I will not apply your patch and check this out. Beside this, I will update to 2.9.3. I just saw that my current version was not in portage anymore. I will post log.txt the next time, sorry I just forgot it and telgram seems to overwrite it once launched again.

I don´t see anything significant, unfortunatly. Shame. Can you try either the jemalloc patch I posted earlier, or as has been mentioned recently in the github thread, build either jemalloc or telegram (or both) with -O3 instead of -O2? Disregard the -O3 thing. Please test the patch if possible. I tested 2.6.3 with the patch and I got the crash, afterthat I recompiled 2.6.3 without the patch because I thought the patch is not fixing the problem. If you like I can build it again with the patch. Should I do that? I see. Nevermind the patch, then. In that case the last thing I can ask of you is a coredump. Build jemalloc, tg_owt and telegram-desktop with FEATURES=nostrip and C(XX)FLAGS=-ggdb as described in https://wiki.gentoo.org/wiki/Debugging And then run telegram like this: sudo sysctl -w kernel.core_pattern=core ulimit -c unlimited telegram-desktop If it crashes, it will say (core dumped), and it will store a dump at ~/.local/share/TelegramDesktop/core. Generate a backtrace with sys-devel/gdb like this: gdb telegram-desktop ~/.local/share/TelegramDesktop/core bt There's more info that can be gathered from a coredump, but without additional context I wouldn't know what to look for, and inspecting it myself would require getting a copy of your binaries along with the coredump... Here's hoping the backtrace is enough. Also please enable the "debugmode" cheatcode as described here: https://github.com/telegramdesktop/tdesktop/issues/16540#issuecomment-872079690 This will give more detail on log.txt... Sorry for asking so many things, and thank you for your patience... Just to be clear, I need to place a file like this: /etc/portage/package.env/dev-libs/jemalloc containing this: nostrip C(XX)FLAGS=-ggdb and the same way for tg_owt and telegram-desktop, correct? Correction, it must be:
FEATURES="${FEATURES} nostrip C(XX)FLAGS=-ggdb
right?
Your file in /etc/portage/env must contain, exactly:
FEATURES="nostrip"
CFLAGS="${CFLAGS} -ggdb"
CXXFLAGS"${CXXFLAGS} -ggdb"
you mean /etc/portage/package.env/<package specific path> and NOT just /etc/portage/env ? It seems to be that I am on the wrong way:
emerge -a1 jemalloc tg_owt telegram-desktop

--- Invalid atom in /etc/portage/package.env/net-im/telegram-desktop: CFLAGS="${CFLAGS}
--- Invalid atom in /etc/portage/package.env/net-im/telegram-desktop: CXXFLAGS"${CXXFLAGS}
The filename should be either /etc/portage/env/<file> or /etc/portage/env/<cat>/<pkg> The former can be used from package.env, to specify the same file for multiple packages. See: https://wiki.gentoo.org/wiki//etc/portage/package.env Understood, it must be /etc/portage/env/<package path> the wikipage was confusing me, sorry .. I am now building, this will take a while. According to the wiki, do I need the files "debugsyms" and "installsources" as well? Just nostrip is fine. "debugsyms" doesn't exist and "splitdebug" is just a fancier nostrip. "installdebug" allows stepping through the source code but isn't necessary for a backtrace. > installdebug
I meant installsources...
It´s all build, debugmode switched on and I am now waiting for the next crash .. let´s see ;) Hnn .. the "nostrip" does not seem to be enabled, gdb tells me: ###### gdp output ####### gdb telegram-desktop ~/.local/share/TelegramDesktop/core GNU gdb (Gentoo 10.2 vanilla) 10.2 Copyright (C) 2021 Free Software Foundation, Inc.

Thanks a ton! This seems like an opengl-related bug within telegram. Upstream has a bug report that's very likely related: https://github.com/telegramdesktop/tdesktop/issues/16540 I'll forward the backtrace along to upstream as it'll probably be helpful, and I'm currently not near my computer to check it out myself. Please keep the coredump (and unstripped binaries) around as it might be useful for further information gathering. Could you mention your current graphics driver (VIDEO_CARDS variable or installed xf86-video-* packages) and version? Also, to prevent crashing, you can disable opengl in settings->advanced->performance as a temporary fix. VIDEO_CARDS="nvidia" x11-drivers/nvidia-drivers-470.57.02 (it was 460.91.03 the last days, just updated) And thank you for you patience with the mistakes of an unexperienced N00b ;) And thank you for picking up this issue at all. Alright, thanks for everything. Unfortunately what I can do to help pretty much ends here. Upstream is aware of the issue now but doesn't know either - they suspect it's either related to the graphics driver or Qt. It might help to generate a backtrace with the debugging symbols for dev-qt/qtgui enabled, but no promises there either. If it's truly a Qt issue, it might be more helpful to wait for the gentoo:kde devs to package the kde patchset for Qt, as that might fix it. In the meantime, the workaround remains: to turn off opengl rendering under settings->advanced->performance. This issues is fixed with newer versions since a certain amount of time. Thanks for confirming! Created attachment 843447 [details]

When maximising a picture in a channel, telegram crashes and I can see this protection fault: telegram-deskto[4253]: segfault at 8 ip 00007f569d6e5ee0 sp 00007ffe410fbcf8 error 4 in libQt5Gui.so.5.15.2[7f569d670000+367000] A second attempt after relaunching telegram-desktop almost works and in most cases it does not fail in all further attempts.
