I just tried it with the latest download from the main page. And it seems to have issues displaying 3440 x 1440 @ 59Hz/60Hz. It can only display it at 49Hz.
However, at the login screen, it will display, by default, at 3440 x 1440 @ 60Hz, so there is no display shown.
On Windows 10, there is no display issues at 3440 x 1440 @ 60Hz
