Comment:
There is some race condition happening in the code path for loading the gtk libs when resizing it immediately after starting it (as will be done by i3 and other tiling manager).

You should be able to start it reliable by starting it in e.g. floating mode.

The offending code path is removed in Telegram 3.0.2.
