JoshStrobl Probably something better to ask the Telegram developers. Loads of tasks filed against their tdesktop repo regarding memory usage: https://github.com/telegramdesktop/tdesktop/issues?utf8=%E2%9C%93&q=is%3Aissue+is%3Aopen+memory+usage+
algent I just installed it from Software Center and I see that it uses around 125 MB, also my conky in the right report same memory usage. What System Monitor are you using?
Nycticorax Can you try the portable version and keep us up to date? It sits here: https://telegram.org/dl/desktop/linux
