Any idea why Telegram stopped working after this update?

Seems Telegram itself wasn’t updated. I don’t (yet) have it installed but I do believe it’s rather fussy about versions.

You might be better using a containerized version unless you are willing to switch branches.

Telegram was crashing due to a corrupted Fontconfig cache, which caused Qt font rendering to segfault. Rebuilding the font cache fixed the issue.

rm -rf ~/.cache/fontconfig
sudo rm -rf /var/cache/fontconfig/*
fc-cache -rv

I don’t know. Could be a bug in the package.

As can be seen in comment above the package has been rebuilt several times and is a pkgrel 7 in testing and unstable.

I’m guessing it’s more of a problem on non-qt desktops. I’m on Plasma and I haven’t had any problems with telegram-desktop yet.
