Q: Desktop background blurred after reboot
Most of the time, after I reboot, my desktop background is the same blurred version of my background that the login screen shows. There is also a dark alpha channel overlaid on the image. When I close a window on a standard Finder desktop, the desktop on my 2nd monitor will change. When I slide desktops, the image will be briefly clear.
Logging out and back in fixes the problem, but I'd like to not have the problem in the first place.

Might be a corrupt .plist.
Do a backup, preferably 2 backups on 2 separate drives.
Go to Finder and select your user/home folder. With that Finder window as the front window, either select Finder/View/Show View options or go command - J. When the View options opens, check ’Show Library Folder’. That should make your user library folder visible in your user/home folder. Select Library. Then go to Preferences/com.apple.finder.plist and com.apple.desktop.plist. Move the .plists to your desktop.
Re-launch Finder by restarting the computer and test. If it works okay, delete the plists from the desktop.
If the same, return the .plists to where you got it from, overwriting the newer one.
Thanks to leonie for some information contained in this.
