I have been using Photoshop CS2 for years on various versions of Linux and Ubuntu. In recent years, I've found that installing it with PlayOnLinux has had the most consistently reliable results.

However, on a fresh install of 13.10, the Photoshop interface looks terrible. The fonts are clunky, and in the image below, it's not an image of a white box on a black backround with a square drawn in a black line. It's actually just a plain white image. The surrounding black area is where ordinarily Photoshop is supposed to be a neutral gray canvas, and the black square is a selection area, which is supposed to be a dotted line.

How do I get Photoshop's proper interface, as I've had with every version of Linux and Ubuntu previous to this?
