Some apps in my dock require two clicks to launch

Some apps simply require two clicks to launch. Other apps show their menu bars but aren't in the correct space. A second click switches spaces and completes the launch of the application.

I completely reinstalled the OS (from macOS recovery), but that didn't fix the problem. Perhaps the cause is a conflict with a third-party app. This is just a small problem, but they can grow into bigger problems. Any ideas?
