Telegram crashes if the other person enables webcam (Mesa crash)
I reported it to telegram bug report here: https://github.com/telegramdesktop/tdesktop/issues/25398 they say it's a mesa bug. Other people are reporting for different reasons here: https://github.com/telegramdesktop/tdesktop/issues/25402 and here: https://github.com/telegramdesktop/tdesktop/issues/25383
apparently, it's the same crash, due to a mesa bug.
Relevant coredump with debug symbols
If I use telegram from flatpak or telegram from official archlinux repo, I have bug. BUT if I use the AUR version (so from the official site), I DO NOT have the bug. Apparently, it's because "flatpak uses mesa from flatpak runtime, official binary uses mesa from your system"
