So i have an ssd and my computer is very fast boot (10 - 15 seconds) and everything loads on startup like the icons and folders and i can open application immediately on startup without almost any lag. But the one problem i have is the desktop background! It will take 30 to 45 seconds to load most times. It will just be a blank black background for a while then the background loads. This is very annoying. How can i fix it?
