The app is completely unusable on my linux machine! It took over the entire screen and I lost control of my cursor. All I managed to do was somehow click on the signup button and that was the end of it. Tried switching back to other apps, but the horrible cursor lag continued. Horrible experience!!
Update: Turns out its a Mono app! So it gracefully died with this limerick:
