Icons from the Launchpad can get permanently stuck on the screen, requiring one of a few obscure workarounds or a logout to correct.

To reproduce:
1. Open the Launchpad.
2. Search for an app that’s not on the current page.
3. Drag the app away and then quickly release it.
4. The icon may get stuck permanently on the screen, on top of all windows.
5. To make it go away, one can:
• Enter wiggly “move mode” in Launchpad
• Kill the Dock or Finder process
