Weird Transparent Shadow Marks on my Desktop Background.

[SashKo_KiD]

Hello,
I've installed a Fedora Transformation Pack (it kinda makes the XP look like a Linux). That Fedora Pack included stuff like True Transparency and other different stuff I can't tell now, since I don't remember but.
I uninstalled the Fedora Pack and installed myself a new Transformation Pack - Flyakite Os X- which turns my XP into an iMac Apple.
The Flyakite also includes many plugins in it, such as: Tiger System preferences, iColor Folder, Visual tool Tip...and others I suppose.
I know for sure that the True Transparency hasn't gone with Fedora's uninstall, not that I wanted it to go, i actually love it.
Well...and the problem is that after some period of working and making different stuff on the computer in my user, there start to appear some weird transparent shadow squared shapes that I can't even remove. It mostly happens during opening and minimazing different windows while i work and browse through the net and other different programs. I use a Downloading Manager called ORBIT. Before I installed ORBIT I had IDM-Internet Download Manager, I kinda noticed that it started to appear when I installed it, the IDM. Then I decided to uninstall it and to install another DL manager instead of it, which is ORBIT like I said. But they wouldn't go away! Why does it happen and how can I make them dissappear?

And here I got you some URLs of screen shots of how these marks look like on my desktop, and also of the installs on my own PC:

Thank you,
