Sorry, but according to the version you specify in this issue, you are using the Telegram for macOS, not the Telegram Desktop.
You can report your issue to the group or to the repository of Telegram for macOS.

If I made a mistake and closed your issue wrongly, please reopen it. Thanks!

Also experiencing this on macOS (Telegram 12.5/12.6, both App Store and direct download via Homebrew). One specific channel renders a completely black/blank message area while all other chats work fine.

Update: Nuking all local data (~/Library/Group Containers/6N38VWS5BX.ru.keepcoder.Telegram/, caches, containers, etc.) and reinstalling did NOT fix it. The issue reappears immediately after re-syncing, confirming it is not a corrupted local cache — the problem is triggered by something server-side in that specific channel being rendered incorrectly by the macOS Swift client.

• Web client (web.telegram.org): works fine
• iOS: works fine
• macOS native (Swift client, both App Store and Homebrew): broken

No custom chat theme is set on the affected channel. This appears to be a rendering bug specific to the macOS Swift client.

@GeiserX This one is about Telegram for macOS, which is a different app.

also having this issue, my gut tells me is that its a premium group, where they probably stop people screenshotting stuff on ios, maybe you and I have a thing running on our macs that "records your screen" and is tripping that same anti screenshot thing?

I know this isn't the right queue, but for those coming from Google, this is the issue. If you're running Screen Sharing or OBS or anything else that records the screen or can record the screen, Telegram's anti-copying tech interacts with MacOS's recording APIs and causes the channel to be rendered grey. As soon as you quit OBS or whatever it is recording your screen, the channel renders normally.

@zulaport This is not about Telegram Desktop, it's about different app on macOS, Telegram Swift. It has a separate repository.
