I was wondering when this issue might pop up :D
I've just issued another build (newer than the duration fix) and it will resize the contents of the window to fit. It's not a perfect solution as it actually scales everything which makes it harder to read, but I tested it at your resolution and I believe its usable until I figure out a better solution. Part of the problem is the two large 512 x 512 preview windows at the top, they can't currently be resized but I will see if there is a way around this.
