Since version 4.8.3 Telegram Desktop needs Qt6 for complete Wayland integration. Although, our package is build against Qt5 yet. Some plugins that tdesktop relies on were not built against the latest Qt, and migration was postponed. > The latest official release (4.9.3) also works on Wayland with system > decorations, and the 4.8.1 Debian package works as well.

You are right but this protocol is an optional part of Wayland. KWin in KDE Plasma implements the protocol, Mutter in GNOME does not. For now, I will block the native Wayland integration and the coming update will prefer Xwayland because of unresolved glitches. The default window frame looks not as intended, it has no context menu, and it can double while switching the checkbox "Use system window frame" in the Settings. Of course, you always can force native Wayland but at your own risk. I will also add a patch restoring the checkbox in all modes.
