How come Custom and Game are blurry now?

The zenzizenzic release changed the default graphics backend to gfx_directx. gfx_directx is meant to default to NOT blurring the image when running at greater than 1x zoom, but it has an option to enable it. When you click on the icon at the top-left of the window, you'll see Options. Click this. The Enable Smooth Draw option makes the screen blurry. If this option is off and the image is still blurry, then you've encountered a bug! Please provide details of your system (such as your OS, DirectX version,and graphics card) by creating a bug report on Bugzilla (or alternatively on the discussion page for this page).
