> It should be created... How are you checking for its presence? Do you have corecollector enabled shoveling core dumps elsewhere?

`core` file is not created. I do not know of any collector. I expect this is something I would have to enable via `runit`.

```
% ls /var/service | grep -v tty | xargs
acpid alsa bluetoothd dbus dhcpcd mpd openntpd udevd wpa_supplicant
```


> Could you try `unset QT_QPA_PLATFORMTHEME` and then run telegram? It fixed for me.

That does not work for me.
```
% unset QT_QPA_PLATFORMTHEME
% telegram-desktop

Maybe it really has to do something with fonts? Could you show me your list of installed fonts?
