Display issues after standby

[frY]

Hey,
sometimes after my mac comes back from sleep i get these display issues shown in the attached pics.

Sometimes i can fix them by just pluging the displaylink device out and back into the usb, sometimes not. In addition if i replug the divice all my usb devices stop working and i have to power off my mac by holding down the power button. :(

Log also attached.

Have you already followed our FAQ about i5/i7 systems? http://www.displaylink.com/support/ticket.php?id=300

That said, the logs show something interesting I have to investigate. Problem with these issues is they are timing related and may not appear on our test systems.
