So i'm using a theme (Simplify8) from DevArt and when I apply it, some of my icons show this weird black line on the left of the icon when I am in any view larger than "Medium Icons" view.

The first image is when the icons are in "Medium Icons" view. When it is in that view, it is fine. The second image is just another zoom level higher (one ctrl + scroll up) and the black line shows. If you look closely, the icons themselves look different. It seems that Windows either switches to a bigger icon set or presents them differently. Minus the black line, this happens regardless of whatever theme I use. The third image is just the largest icon view so you can see the black line more clearly.

I've contacted the creator of the theme and he has no idea how to fix it. I'm hoping someone here could give me some insight on what is going on as I really like this theme and this is my only problem with it.

I have a bit of experience with Windows Style Builder so if you know what I have to change in there, I probably can. The OS is W8.1 and it is a completely fresh install shy of UltraUXThemePatcher and applying the theme.

Thanks for the help.
