The new dev version 0.9.3 is already out! You can update in Settings or download this new version from the bottom of https://desktop.telegram.org/#dev-version page.

This one should render your conversations list, emoji and stickers panel and almost all other parts a little bit faster. Especially it could be noticed if you own not a very fast PC or you run OS X with Retina display.

I remind you that the «dev version» update channel is less stable but it gets all new features (and bugs, and crashes 😄) a little bit faster, than the stable one.
