10-second delay launched "Metro" apps

[KenB]

When the latest DisplayLink drivers are installed on my computer, all "Metro"-style Windows 8 apps have a long startup delay. Removing the driver restores normal startup time.

Clicking the tile displays the solid-color screen with the large app icon, but the "busy" animation that normally shows beneath the icon does not appear for 7-12 seconds. Once the busy animation appears, the app typically shows its main screen within 0.5-2 seconds.

This weekend, I reinstalled Windows 8 and all apps three times to isolate this. It is the driver and nothing else. (I had suspected group policy for our domain, Hyper-V, and a few other things, but they aren't it.)
