If I click on the KDE Applications Launcher and then change desktops while the Launcher popup is visible, the Launcher popup disappears (normal) but then does not pop up when I click on the Launcher (bad); the Launcher behaves normally otherwise. This behavior is only for my account; using other accounts on the same machine the Launcher behaves normally.  When new launchers are installed on the taskbar they behave in the same way.

Any ideas on how to investigate?

System:
Fedora-27
KDE Plasma 4.11

A similar thing happens with applets in the Tray. When a session starts, clicking on the applet's tray icon produces a pop-up menu, but as soon as I change desktops with a pop-up visible, left clicking produces only a blue bar above the icon. Right clicking works properly for all the applets. This behavior applies to Audio Volume, Network Manager, Clipboard, Device Notifier, Software Updates, and Notifications, though not to the Kalarm applet.

All very strange. Any ideas on how to investigate?
