MacOS – Finder Window flash and disappears on unminimize

findermacos

You can clearly see what's wrong with Finder in the GIF. When I click the Finder window, it appears to restore the window, and then it's gone. This usually happens after a while. It's very annoying, a quick fix is to Force Quit Finder, and I can restore those windows again.

  1. There is only 1 Desktop spaces enabled
  2. I have tried removing ~/Library/Preferences/com.apple.finder.plist
  3. My MacBook's version is macOS Sierra 10.12 latest version. If my memory is correct, I have seen this kind of problem before updating to Sierra (when I was using El Capitan)
  4. I also tried removing the saved state from ~/Library/Saved Application State/com.apple.finder.savedState

Is there anyway to fix this? Please tell me if more information or log files are required. Thank you.

After Finder window disappear on unminimize, press Cmd-Ctrl-F. The Finder window (and Safari window too where there is the same problem) reappear and go to full screen. Press Cmd-Ctrl-F one more time and it returns to normal size.
