So a few years ago, on my old computer, I fiddled around with the system settings and made it so that almost EVERY non-active window, regardless the application becomes transparent when inactive. After years of being annoyed by this while watching movies and surfing the web, I decided to try and fix it. The only problem is that I have no idea what I did to get it this way to begin with, cannot find any software anywhere, and so on- though I did find it interesting that the rule was carried onto my new computer while migrating systems- so clearly the code/app is in here somewhere. My question is - any idea how the hell I can go back to a world of opaque windows?! Any magic kill switch codes? I know there are perhaps far too many variables to even come to a conclusion, but thought I'd give it a try. I appreciate any ideas/input! THANKS!
