Description of problem:
When using alt-tab to switch the active app, if the dialog or whatever it is called is displayed on the second monitor of a dual monitor setup (no xorg), the third tab will blank the icons. Meaning that once I've hit tab 3 times in an attempt to cycle through the running apps the icons are gone, just a grey window. I can continue to cycle and if I've counted where I wanted to end up can get the app I want. This never happens if the alt-tab window shows up on the primary monitor (the one with the 'task bar?')

Version-Release number of selected component (if applicable):

Steps to Reproduce:
1. Alt-Tab on secondary monitor

Blank alt-tab 'window'

Continuously display all running program tab icons / screens
