Here is a screenshot of the issue with the version of Ice that comes packaged with WindowBlinds
Looking at the startbutton and taskbar you don't even have the Ice WB loaded.
looking at you windows setting window that isn't the original Ice WB either. Ice doesn't have a Black BG. It also doesn't have black text. You want help on a modified version. Can't do that.
Looking at the windowblind screen shot you may have more but are showing at least 3 versions of the Ice WB.
You said you did what was asked in reply #6. I suggest you do it again and show the WB image again only showing 1 version of Ice.
On a different note. you are using a Windows 10 Insider Preview update. Anything can happen doing that.
