Mac Pro and dosdude1 patch

Ok, so not really urgent, but I got this Mac Pro 3,1 (2008) a week ago and I heard the seller say that he got the dosdude1 Catalina patch on the Mac Pro. I tested it and it works fine, only problem being that all transparency elements (dock, volume controls, etc.) are plain white, not transparent. If anyones wondering, my graphics card is a ATI Radeon HD 5770 (1gb) (I'm using a Mini DisplayPort to VGA adapter as well). If you have the answer, please tell me! Thanks in advance!
