I used to be able to drag images to my desktop. This now seems broken. Here's a video of the problem. Basically, I'll drag an image (doesn't matter from where) to my desktop and it will not appear as a file.
Note: I have tried relaunching finder with
cmd+alt+esc and with the terminal commands:
defaults write com.apple.finder CreateDesktop true killall Finder
