Comment 12 for bug 1290575

Just rebooted pc to try & replicate this problem for a 3rd time. I opened as many applications as I could remember having open the other times. So far I can replicate application windows flashing non stop after trying to start a VM in "QEMU emulator version 1.7.0 (Debian 1.7.0+dfsg-3ubuntu6)", which stops when I close it, I'm positive the first two times this bug arose the flashing of windows happened but on the third time no greeter taskbar applications were shown.
