Yah AeroGlass pretty much solved this issue for me. I always use a Personalization theme that generates Automatic Colors for the taskbar and window borders, it does not really work without Glass. Also I found out, if you use any Windows 8 Themes, it will maintain all of the settings for that theme including how long the wallpaper stays. If you had 10 seconds set, it changes after 10 seconds in Windows 10. The settings for Automatic Color and desktop slideshow time are ridiculously hidden from Windows 10 users. You are totally at the mercy of whatever desktop Theme you use. I used to create my own themes for Windows 7 and 8, can't do that so much under Windows 10.
