It very much looks and behaves like it is a wrapper around the web interface.Whether it is or not, can't say for sure.

That said, I switched back to the web interface because I can use custom stylesheets on there, and I can't on the "native" version. The normal interface, with the black text on the white, is basically unusable by me. It's just blinding and difficult to work with. Slack severely needs a "night mode", and with some custom styling, I was able to make the web version actually usable and useful.

That said, I have not had any freezing or slowdown issues with the web version in Chrome. I can leave it running for days at a time and it's just fine.
