Hackintosh - black rectangle

I've been trying to build my own Hackintosh, and it's almost functional. Still not stable: it may or may not boot. But one thing is consistent: this black rectangle around the mouse cursor.

UPDATE: It's an Accessibility setting. In the Accessibility control panel, go to the Zoom settings, and then click on the More Options… button. Uncheck "Show preview rectangle…".
