Tdesktop: Bad text alignment

[SleeplessSloth]

Steps to reproduce

1.1. Either: Send or receive a message with a link or a word with repeated letters
1.2. Or: Send or receive a message in a channel with buttons underneath
1.3. Or: Forward a message

1. Watch the client fail to align the text correctly

Expected behaviour

The text should be shown normally

Actual behaviour

1. The message is shown with each letter on a new line
2. The buttons under a message in a channel are unreadable
3. The name of the person who wrote the message originally is replaced with ...

What I tried

1. Reset fontconfig to default
2. Change Telegram's interface scaling
3. Change themes
4. Create a new user account

Configuration

Operating system: Arch Linux

Version of Telegram Desktop: 1.8.15

I'm seeing this with the Flatpak of 1.8.15, but not the snap.

@SleeplessSloth Known issue, related to Qt update. You must rebuild Telegram Desktop from sources against new version of Qt.

Rebuilding from source solved the issue, thanks! I guess my beta version of Qt was the culprit. Thankfully, rebuilding is very easy to do on Arch, in my case it was a simple matter of yay -G telegram-desktop; cd telegram-desktop; makepkg -sic
